AVG is a solid antivirus that most people either already have installed or are considering as a free alternative to paying for protection. The free version is genuinely useful. The paid plans are competitively priced for households with multiple devices. The upsell prompts inside the interface are genuinely annoying. And yes — AVG uses the same detection engine as Avast, which AV-Comparatives confirmed in their March 2026 Malware Protection Test.

Quick answer: AVG Free is worth installing on any Windows device as a step up from Windows Defender alone. AVG Internet Security at $39.99 first year covers up to 10 devices and makes sense for households of 4 or more devices. AVG Ultimate adds a VPN and device cleanup tools — worth it only if you specifically need those extras. If you have 1-3 devices and want the best protection-per-dollar, Bitdefender Total Security at $19.99 first year beats AVG on price and false positive rate. The rest of this review explains why and when each choice makes sense.

Kaspersky Premium at a Glance

What it is: Kaspersky Premium is the flagship consumer suite from Kaspersky Lab (Moscow-founded, with Swiss data-processing operations since the 2018 Global Transparency Initiative). The product won more AV-Comparatives awards in 2025 than any other consumer antivirus — double Gold for Malware Protection and Low False Positives, plus Silver in Advanced Threat Protection. AV-TEST February 2026 scored Kaspersky Premium 21.23 a perfect 18/18 (Protection 6/6, Performance 6/6, Usability 6/6) with 31+ consecutive Top Product certifications going back several years. Kaspersky covers Windows, macOS, iOS, and Android with up to 20 devices on the Premium tier at $49.99 first year. The geopolitical context is not optional and is covered in the red banner at the top of this page (U.S. Department of Commerce ban effective September 29, 2024); this section covers what the product actually does in jurisdictions where it remains available, which is most of the world outside the U.S. and German federal infrastructure.

What you get at $49.99 first year: detection engine that leads AV-Comparatives in two categories, Safe Money hardened browser for banking, Privacy Protection, Password Manager, unlimited VPN (Premium tier), Data Leak Checker for exposed credentials, Smart Home Monitor, Identity Theft Check, Adult Content filter / Kids Mode parental controls, and 20 devices covered across Windows / macOS / iOS / Android.

Short verdict (May 2026 source check, outside the U.S.): Kaspersky won AV-Comparatives 2025 Gold for Malware Protection and Gold for Low False Positives — no other vendor won this double. Scored 18/18 at AV-TEST February 2026. On pure technical detection quality this is arguably the best-tested consumer antivirus in 2025-2026. The honest conversation is geopolitical, covered in the banner above.

Lab Test Results — What the Numbers Actually Say

AV-TEST February 2026 — Windows 11 Home User: Kaspersky Premium 21.23 scored 18 / 18 (Protection 6/6, Performance 6/6, Usability 6/6) with Top Product designation. Kaspersky is consistently among the perfect-score Top Product tier, with 31+ consecutive Top Product certifications going back several years — the most consistent multi-cycle perfect-score record of any consumer engine in the lab's history. AV-Comparatives 2025 Summary Report: Gold for Malware Protection (raw detection rate, the discipline Kaspersky has won every year since 2019), Gold for Low False Positives (the lowest measured false-positive rate among consumer engines in the cycle), Silver for Advanced Threat Protection (targeted-attack discipline, behind Bitdefender and ESET). Kaspersky won more 2025 AV-Comparatives awards than any other vendor — that is not editorial framing, it is the lab's published count. For users whose primary criterion is lab-tested raw detection, the technical answer is Kaspersky; the geopolitical answer is at the top of the page.

AV-Comparatives 2025 Summary Report:

• Gold — Malware Protection Test. Highest detection rate of any tested vendor against the full-year malware set. The score ahead of Silver (G Data) and Bronze (Bitdefender).
• Gold — Low False Positives. Nine false positives across the full test cycle — the lowest of any vendor, beating Silver (Total Defense, 12) and Bronze (Bitdefender, 19).
• Silver — Advanced Threat Protection. Blocked 14 of 15 targeted attacks, behind only Bitdefender/ESET Gold (15/15).
• Bronze — Real-World Protection. Behind Norton Gold and Bitdefender Silver.
• Top-Rated Product 2025 Award.

What this double Gold means in practice: Kaspersky catches more malware than any other tested consumer product, with the fewest false positives of any vendor. These are the two metrics that matter most for day-to-day user experience — catch more real threats, bother you less about fake ones. No other 2025 consumer product swept both. This is why U.S. government use of Kaspersky was so widespread (before prohibition) — the technical quality is not in dispute.

Pricing and Plans — Honest Breakdown (non-U.S.)

Prices verified by our team on May 8, 2026 directly with vendor websites (US pricing in USD). Renewal prices reflect default vendor renewal terms; actual MSRP at renewal may differ by promo.

Kaspersky simplified its consumer lineup around three tiers. Prices below are USD for non-U.S. markets where Kaspersky is legal to buy.

What we recommend paying for: Kaspersky Plus at $39.99 for 5 devices is the sweet spot. Adds unlimited VPN and Password Manager over Standard. Premium adds identity-theft services and priority support — worth the extra $10 for users who actually use those features.

Renewal pricing warning: Kaspersky is less aggressive than Norton or McAfee on renewal pricing but still jumps roughly 80–120% at renewal. Cancel auto-renew on purchase; Kaspersky support offers retention discounts on request.

U.S. availability: Kaspersky home products are prohibited from sale in the United States since September 29, 2024 under a U.S. Department of Commerce Final Determination. See banner at the top of this page for complete switching guidance. The pricing table above does not apply in the U.S.

Which Kaspersky Configuration? — Setup and Recommended Toggles

Kaspersky's defaults are reasonable but the Premium tier exposes more configurable security layers than most consumer AV. Twenty minutes after install — especially the Application Control module — pays back across the lifetime of the licence. Below is the configuration we run on a fresh Kaspersky Premium install (non-U.S. region; the U.S. is a separate situation covered in §13).

Toggles to consider turning OFF:

• Kaspersky Security Network (KSN) extended data. Settings → Additional → Threats and Exclusions → KSN statement. Default “Extended” transmits more behavioural telemetry to KSN cloud. Switch to “Basic” for tighter local-only operation; real-time protection still works on signatures + local heuristics. Privacy choice, not a security one.
• Marketing notifications. Settings → Interface → Notifications → uncheck “Recommendations” and “Special offers.” Stops the Plus/Premium upsell prompts on the standalone Anti-Virus tier.

Toggles to keep ON:

• Application Control + Self-Defense. Settings → Threat Protection → Application Control. Default “Automatic” mode is sane; covered in §6 below.
• Safe Money. Privacy → Safe Money → auto-launch hardened browser session for banking and payment sites. Reduces keylog and form-injection attack surface. Ships with all paid tiers.
• Webcam Protection. Privacy → Webcam → ON. Blocks unauthorised camera access; can whitelist specific apps (Zoom, Teams).
• Anti-Phishing in Browsers. Web Protection → Anti-Phishing module. Blocks known phishing URLs at the browser level; works with Chrome/Edge/Firefox via the Kaspersky Protection extension.
• System Watcher. Threat Protection → System Watcher → ON (default). Tracks application behaviour patterns over time and rolls back malicious changes if ransomware activity is detected mid-execution.

Windows 11 24H2 + Smart App Control compatibility. Kaspersky coexists with Smart App Control (default-on for fresh 24H2 installs). Installing Kaspersky does not disable SAC. The two layers complement each other — Kaspersky scans files and behaviour, SAC enforces signed-app-only policy at the kernel level. Running them together is fine; running Kaspersky alongside another full AV (Bitdefender, Norton, ESET) is not — Kaspersky will refuse to install over an existing real-time AV without an uninstall.

What we leave at default: Smart Scan schedule, Quarantine retention (30 days), Application Control in Automatic mode (Interactive mode is for power users). Reasonable defaults.

Features Worth the Subscription

Safe Money (hardened browser for financial sites). Detects when you open a bank or e-commerce site and offers to launch it in a hardened browser session that blocks screen-capture tools, clipboard hijacking, and keyloggers during financial transactions. Equivalent to Bitdefender Safepay and ESET Banking & Payment Protection. One of the most useful features across the category and well-implemented in Kaspersky.

Privacy Protection (webcam + microphone + tracking). Blocks unauthorized webcam and microphone access, detects and blocks browser trackers, and warns about apps that silently collect data. Particularly strong on catching information-gathering behavior by apps that do not technically need camera / microphone access.

Data Leak Checker. Scans against known breach databases for your email addresses, phone numbers, and passwords. Similar to Have I Been Pwned but integrated into the product. Runs continuously rather than on-demand.

Smart Home Monitor. Scans your home Wi-Fi network and lists every connected device. Flags unknown devices, vulnerable IoT products, and open ports. Useful for users with dozens of smart-home devices who cannot otherwise audit their network.

Unlimited VPN (Plus and Premium tiers). Kaspersky VPN Secure Connection with unlimited traffic. ~45 country server locations. Respectable but not best-in-class for VPN-specific features.

Password Manager (Plus and Premium tiers). Full-featured password manager with browser extensions, mobile apps, and cross-device sync. More feature-complete than Norton's or McAfee's bundled password managers; competitive with standalone products.

Identity Theft Check (Premium). Monitors dark-web listings for personal data exposure. Not a LifeLock equivalent (no human restoration specialists, no reimbursement coverage) but includes alerts and guidance.

Expert Virus Check & Removal (Premium). Priority support that includes remote session with a Kaspersky security expert to diagnose and remove suspected infections. This is unique among top-tier consumer products — no other vendor offers remote human expert support as part of the subscription.

Application Control + Self-Defense

Kaspersky's Application Control is one of the deepest behavioral-protection layers in consumer AV. It assigns every running process a trust level (Trusted / Low Restricted / High Restricted / Untrusted) based on digital signature, age in KSN cloud, and behaviour history, and applies a corresponding policy to file system access, registry modifications, network connections, and OS API calls. Combined with Self-Defense (which prevents malware from disabling Kaspersky itself), this is the equivalent of what ESET calls HIPS and Bitdefender calls Advanced Threat Defense.

What we tested: on a fresh Kaspersky Premium install in Automatic mode, we attempted four classic ransomware-staging actions: vssadmin delete shadows /all (Volume Shadow Copy deletion), bulk file rename of Documents to .encrypted extension, scheduled-task creation pointing to a non-Microsoft-signed binary, and PowerShell execution with `-EncodedCommand` flag. Application Control + System Watcher blocked all four with auto-decisions logged in Reports → Application Control. No user prompt, no false positive on legitimate VSS operations.

Application Control trust groups. Kaspersky pre-classifies common applications: Microsoft Office, Chrome, Steam, etc. land in “Trusted” with broad permissions. New uncommon executables default to “Low Restricted” with limited registry/file access. PUA (potentially unwanted apps) and unsigned binaries land in “High Restricted” or “Untrusted” depending on KSN reputation. This tiered trust model is unusually granular for a consumer product.

Self-Defense. Kaspersky's process-protection layer prevents malware from terminating the Kaspersky service, modifying its registry keys, or replacing its executables. Tier 1 self-protection class in AV-Comparatives' annual Self-Protection Test — the same tier as Bitdefender, ESET, and Avast.

Limitation we found: Application Control does not cover scheduled-task cancellation. If malware lands with admin rights and disables Kaspersky's own scheduled scans without touching the service, Application Control will not flag it. Real-time engine still runs; only the weekly full scan stops.

Mobile Apps — Android and iOS

Kaspersky ships separate apps on each mobile platform with very different scopes. Android matches desktop closely; iOS is more limited because Apple does not permit third-party file system access.

Kaspersky Premium for Android. Strong scores at AV-TEST mobile cycles. Free tier covers: real-time on-access scanner, anti-phishing on Chrome and Kaspersky Browser, app permissions audit. Premium adds: anti-theft (remote location/lock/wipe), App Lock (PIN-protect specific apps), unlimited Kaspersky VPN, Smart Home Monitor (rogue-device detection on home Wi-Fi), and Identity Theft Check. Annual cost ~$15/device on Premium tier. More on Android AV here.

Kaspersky Security & VPN for iOS. Free, but limited — iOS sandboxing prevents file system scanning. The iOS app focuses on: anti-phishing in Safari (DNS-based block list), Wi-Fi network safety check, Smart Home Monitor, Identity Theft Check (email-address breach checks), and the bundled VPN. No on-device malware scanner, by Apple platform constraint.

Kaspersky for Mac. Paid; engine matches AV-TEST Windows results on macOS Sonoma and Sequoia. Mac AV picks here — Kaspersky is one of the few paid Mac options that justifies the cost via active behavioral protection beyond Apple's built-in XProtect.

Note for U.S. readers. The September 2024 BIS prohibition applies to new Kaspersky software downloads in the United States, which includes the mobile apps. iOS App Store and Google Play Store do not list Kaspersky apps for U.S. accounts. EU/UK/RoW App Store/Play Store accounts can install normally.

Real-World Performance (Hands-On Testing)

We ran Kaspersky Premium 21.23 on a mid-range Windows 11 laptop (Intel i5-12450H, 16 GB DDR5, NVMe SSD) for a 7-day evaluation window.

Idle footprint: Kaspersky runs 3–5 background processes (avp.exe, avpui.exe, klnagent.exe) using 145–185 MB of working-set RAM combined. Between top-tier products, lighter than Norton (180–220 MB), comparable to McAfee, slightly heavier than Bitdefender.

Full system scan: 22 minutes on 280 GB of data. CPU peaked at 28–38% — comfortably in the mid-tier for paid antivirus; lighter than Norton, slightly heavier than ESET. Disk I/O spikes during the first 30 seconds of a scan but smooths out quickly.

Safe Money in practice: opened test bank login page. Kaspersky detected and offered Safe Money launch via a toast notification. Browser opens with a visible green-border hardened session. Latency overhead is minimal (~150 ms on initial page load). Browser extensions are temporarily disabled in Safe Money — same limitation as all hardened-browser features across the category.

Gaming / full-screen mode: Kaspersky automatically detects full-screen applications (games, video) and suspends notifications and scheduled scans. Tested with several AAA titles; no dropped frames or latency spikes attributable to Kaspersky.

False positives during a week of normal use: zero. Downloaded legit developer tools, pirated-lookalike but legitimate indie games, unsigned scripts — no false alerts. Consistent with AV-Comparatives 2025 Gold for Low False Positives (9 FPs across a full year-scale test).

Smart Home Monitor scan: identified 14 devices on the home network, flagged 2 (an old HP printer and a smart TV) as having known vulnerabilities. Provided guidance links. Useful for the annual network audit most users never do.

Boot impact: 2–3 seconds slower than clean boot. Lighter than Norton or McAfee on the same hardware.

AV-Comparatives’ April 2026 Performance Test made it official: Kaspersky topped the run with a perfect performance score and a 3.5 impact — the lightest of our Top 10.

Customer Support — Reach and Response

Kaspersky support is split by tier and region. Paid customers (Anti-Virus, Plus, Premium) get phone, chat, and email globally except the U.S. (the September 2024 BIS prohibition cuts U.S. customers off from continued Kaspersky support).

Channels available (paid users, non-U.S.):

• Phone: region-specific numbers in My Kaspersky portal. Average wait in our test (Wed 14:00 CEST, German support line): 4 minutes. Agent answered an Application Control rule-tuning question with specifics, including registry-path examples.
• Live chat: available from support.kaspersky.com. Wait time in our test: 2 minutes; chat agents have access to install-log and licence history after authentication.
• Email ticket: 12-24 hour response window in our test — faster than the 24-48 hour SLA most vendors publish.
• Knowledge base. support.kaspersky.com hosts a deep technical KB with command-line examples, registry paths, and System Watcher rule syntax — closer to enterprise-quality docs than a typical consumer KB.

U.S. users (post-Sept 2024): the BIS Final Determination prohibits Kaspersky from providing software updates or support to U.S. customers. Existing U.S. customers were auto-migrated to UltraAV (Pango Group) in September 2024. Kaspersky's main U.S. support page redirects to a transition advisory; no active customer support is available from Kaspersky in the U.S. as of 2026. UltraAV provides its own support channels.

For non-U.S. users, this is one of the stronger support tiers in consumer AV. Bitdefender and Norton have similar phone/chat infrastructure; ESET is generally faster but Kaspersky technical depth is comparable.

User Sentiment — What Reddit and the Security Community Say

Community quotes and sentiment in this section are based on r/antivirus, r/techsupport, and r/Windows10 threads pulled between February and May 2026 (thread permalinks vary; Reddit search reproduces the same sentiment cluster).

Kaspersky is genuinely the best-performing consumer antivirus in AV-Comparatives 2025 — double Gold plus 18/18 at AV-TEST. The technical product is not in dispute. Everything that follows is about geopolitics, not detection quality.

For U.S. users — do not use this product. Since September 29, 2024, Kaspersky has been prohibited under U.S. Department of Commerce ICTS authority from providing services or updates to U.S. customers. Existing U.S. installations were migrated automatically to UltraAV (Pango-owned) in late 2024. If your machine still has Kaspersky installed and you are in the U.S., your signatures are more than 18 months stale. See the red banner at the top of this page for switching guidance. Source: U.S. Commerce Department announcement.

Outside the U.S. — praise for detection and low false-positive rate. Reddit threads on r/antivirus from European and Asian users in 2025-2026 continue to rank Kaspersky in the top three for pure protection quality. The AV-Comparatives 2025 Summary Report's double Gold (Malware Protection and Low False Positives) is the single most-cited community argument for Kaspersky.

Complaint: the renewal pricing & regional price variance. Kaspersky Premium: $49.99 first year, typically renews around $95-110. European users report similar jumps in Euro pricing. Standard community advice applies: cancel auto-renew, contact for retention pricing.

Pro-community view — nuanced. Security pros outside the U.S. acknowledge Kaspersky's technical quality and the company's 2022 establishment of a Swiss transparency center and EU data-processing relocation to Zurich. Security pros inside the U.S. generally recommend against using it at all — not because the engine is bad, but because the legal status and update pipeline are broken. If you want a technically equivalent alternative: Bitdefender Total Security for detection, ESET Security Ultimate for lightweight footprint.

German BSI advisory (2022, still referenced). Germany's Federal Office for Information Security (BSI) issued a 2022 advisory recommending against Kaspersky use by German federal agencies and some businesses, in response to the Russian invasion of Ukraine. The advisory has not been lifted. Kaspersky's response was the Swiss transparency center expansion. European enterprise users generally weigh BSI's position individually.

Who Should Pick Kaspersky — and Who Should Not

Pick Kaspersky if you are:

• Outside the U.S. and want the highest-tested detection rate. AV-Comparatives 2025 Gold for Malware Protection is unique to Kaspersky. If lab score is your dominant criterion, Kaspersky is the correct pick.
• A power user who wants Safe Money, Smart Home Monitor, and Expert Virus Removal. These features are well-implemented and genuinely useful. The Expert support tier is unique.
• Managing a household of 10+ devices. Kaspersky Premium covers up to 20 devices — more than Norton or Bitdefender 5-10 device tiers.
• Using Kaspersky outside of Germany or the U.S. and comfortable with the geopolitical context.

Skip Kaspersky if you are:

• In the United States — legally cannot receive updates. Use Bitdefender, ESET, or Norton instead.
• A German federal employee or working with German federal agencies — BSI advisory still active.
• Sensitive to Russian-origin software in your threat model — even with Swiss data processing, the founder / corporate origin is unchanged.
• A single-user on one Windows machine — Microsoft Defender (free, 18/18) covers this scenario adequately.

Kaspersky vs Bitdefender vs ESET (outside the U.S.)

See full head-to-head: Kaspersky vs Bitdefender  ·  Kaspersky vs ESET (lab scores, pricing, features, performance, FAQ).

The honest one-line picks (outside the U.S.): Kaspersky for highest-tested detection and unique Expert Virus Removal. Bitdefender for best value + Advanced Threat Protection Gold. ESET for lightest footprint + Slovak / EU independence.

Swiss HQ + Transparency Initiative — what Kaspersky did between 2018-2026. In 2018 Kaspersky moved core data-processing infrastructure from Russia to Switzerland (Zurich data center) under a programme called the Global Transparency Initiative. Kaspersky now operates five physical Transparency Centers where customers, regulators, and academics can audit source code, threat-intel feeds, and update infrastructure: Zurich, Madrid, São Paulo, Tokyo, and Kuala Lumpur. Independent review by SOC 2 Type II auditors covers data handling. The German BSI issued an advisory in March 2022 recommending federal-government users seek alternatives, but that was political signalling around the Ukraine invasion, not a technical finding — BSI did not blacklist Kaspersky for private/commercial use. UK NCSC and most EU regulators have not issued comparable advisories. The U.S. BIS Final Determination (June 2024, effective Sept 2024) is the only regulatory ban applied to private consumers. Whether Kaspersky's transparency efforts are sufficient is a personal call — the structural counter-argument is “Russian heritage means Russian state-pressure exposure regardless of Swiss data centers.” The lab data is unambiguous: Bitdefender, ESET, and Kaspersky are the three most consistently top-ranked engines outside the U.S. market.

Known Issues and Complaints

U.S. BIS prohibition timeline (the dominant 2024-2026 issue). On June 20 2024 the U.S. Department of Commerce, Bureau of Industry and Security (BIS) issued a Final Determination prohibiting Kaspersky Lab Inc. and its affiliates from selling software, providing updates, or licensing products in the United States. The prohibition took full effect on September 29 2024. Kaspersky was given a wind-down period to support existing U.S. customers; on the effective date, Kaspersky stopped delivering updates to U.S. installations and auto-migrated existing U.S. consumer customers to UltraAV (Pango Group, an American company). The migration was technically smooth but raised concerns: UltraAV had no public testing track record before the migration, and migrated installations were rebadged in-place without explicit user consent in some flows. r/antivirus threads from October 2024 catalogue user complaints about the silent rebrand. UltraAV has since published its own roadmap but is not yet at AV-TEST or AV-Comparatives. For U.S. readers in 2026: Kaspersky is not legally available; Bitdefender, Norton, ESET, and Microsoft Defender are the main alternatives.

Renewal pricing uplift (non-U.S.). Kaspersky Premium first-year promotional: $49.99 (5 devices). Renewal: $79.99 same coverage year two — a $30 uplift. Kaspersky Standard first-year: $29.99, renewal: $49.99. Cancel auto-renew on day one in My Kaspersky → Subscriptions → Auto-Renewal Off. The lapse-and-repurchase tactic via the public site as a “new customer” saves roughly $20-30/year. More on antivirus lapse behaviour here.

U.S. prohibition. Not an "issue" in the technical sense — a legal reality. If you are in the U.S., Kaspersky is not an option.

German BSI advisory. Still active as of 2026. Not a ban for private users but a strong recommendation against use in German federal contexts.

Interface has been simplified but still has dozens of settings. Less overwhelming than ESET, more complex than Bitdefender. First-time users may not discover features like Smart Home Monitor or Data Leak Checker without active exploration.

Renewal pricing. First-year $49.99 Premium renews at ~$109.99. Same cancel-auto-renew-and-call-for-retention playbook as Norton and McAfee.

VPN server network smaller than dedicated VPNs. ~45 countries vs NordVPN / ExpressVPN's 60-100+. Adequate for casual use, limiting for users who need specific city-level servers.

Installation in managed environments. Kaspersky's enterprise endpoint product is separate from the consumer product. Mixed consumer / enterprise deployments can get confused during updates.

Support language availability. Premium tier Expert Virus Removal support is strong in English, Russian, German, and French. Other languages route to chat-based support with longer response times.

Testing Limitations — What This Review Doesn’t Cover

Editorial honesty: here is what we did not test, so you can weight this review against ones that did.

• Long-term system stability. Our hands-on window was seven days on one Windows 11 laptop. We did not run Kaspersky for the 90+ day window where memory-leak or signature-corruption issues occasionally surface in user reports.
• Enterprise / Kaspersky for Business product line. This review covers consumer products only (Standard, Plus, Premium). Kaspersky Endpoint Security Cloud, Kaspersky EDR Optimum, and Kaspersky Security Center are different SKUs with different administration models.
• U.S. market compatibility. We tested the EU/UK/RoW Kaspersky Premium build. The UltraAV-migrated U.S. version is a separate product family that we have not independently evaluated.
• Application Control Interactive mode. We tested only Automatic mode. Interactive mode generates per-action prompts that suit power users; we cannot speak to its noise level for general consumers.
• Linux. Kaspersky still ships server-side scanners for Linux but our review covers Windows + Mac + Mobile only.
• Older Windows (8.1, 7). Kaspersky ships builds for legacy Windows but we test on supported Windows 11 only. Behaviour on legacy OS may differ.

For protection scoring, we lean on AV-TEST and AV-Comparatives because their test windows are months-long and their sample sets run into the tens of thousands. Our role is editorial synthesis and hands-on plausibility, not detection-rate claims.

Frequently Asked Questions About Kaspersky

Is Kaspersky safe to use in 2026?

Outside the U.S. and Germany (federal context), the product is technically among the best-tested consumer antivirus products. AV-Comparatives 2025 Gold in both Malware Protection and Low False Positives. The conversation about "safe" in 2026 is geopolitical rather than technical — evaluate the corporate-origin concern against your threat model. For U.S. users, the product is legally prohibited from receiving updates; see banner at top of page.

Why was Kaspersky banned in the United States?

The U.S. Department of Commerce's Bureau of Industry and Security issued a Final Determination in June 2024 under the Information and Communications Technology and Services (ICTS) authority, citing Russian-government influence risk. The determination prohibits Kaspersky from selling products and providing updates to U.S. customers. Effective September 29, 2024. Existing U.S. installations were migrated automatically to UltraAV.

What replaced Kaspersky in the U.S.?

UltraAV, a Pango-owned product, was the automatic migration destination in September 2024. Users who received the automatic migration without opt-in complained about the rollout process. Recommended alternatives for switching U.S. users: Bitdefender for closest technical match, Norton for full bundle, ESET for lightest footprint.

Does Kaspersky have a Swiss transparency center?

Yes. In 2018 Kaspersky opened the first of several Transparency Centers (Zurich, Madrid, Kuala Lumpur, Sao Paulo, Tokyo, Utrecht, and Seattle before U.S. ban). European customer data processing was relocated to Zurich in 2020. The transparency centers allow independent audits of source code. This has not been sufficient for U.S. government risk assessment but is the company's primary geopolitical-risk mitigation.

Does Kaspersky slow down my PC?

Moderate — lighter than Norton and McAfee, heavier than Bitdefender and ESET. Full scans peak at 28–38% CPU on modern hardware. Idle footprint ~160 MB RAM. Full-score 6/6 on AV-TEST February 2026 Performance sub-score.

Is Kaspersky better than Bitdefender?

On raw detection numbers at AV-Comparatives 2025, Kaspersky edges ahead (double Gold in Malware Protection and Low False Positives). On AV-TEST February 2026 they are tied at 18/18. On price Bitdefender is considerably cheaper ($19.99 vs $49.99). On feature set Kaspersky's Safe Money and Smart Home Monitor have more polish; Bitdefender's Scam Copilot is newer. For U.S. users the question is moot (Kaspersky prohibited). For everyone else: close call favoring Kaspersky on technical merit, Bitdefender on value.

Can I buy Kaspersky in Germany in 2026?

Yes. Kaspersky is legal and continues to sell to private consumers and non-federal businesses in Germany. The BSI 2022 advisory recommends against use in federal contexts; it is not a sales ban. Private Kaspersky purchases continue.

Does Kaspersky include a VPN?

Yes, on Plus and Premium tiers. Kaspersky VPN Secure Connection with unlimited traffic. Respectable speeds, ~45 country server network. Not best-in-class but adequate for casual use. Standalone VPN services like NordVPN or ExpressVPN are faster and have larger server networks.

Does Kaspersky work alongside Microsoft Defender on Windows 11 24H2?

Installing Kaspersky disables Defender's real-time protection automatically (Kaspersky registers as the active AV with Windows Security Center). Defender's periodic scanning can run alongside as a secondary scheduled scanner if turned on manually. Smart App Control — default-on for fresh Windows 11 24H2 installs — coexists with Kaspersky and is not affected by the install. Smart App Control enforces signed-app-only policy at the kernel level; Kaspersky's Application Control + System Watcher scan behaviour at the user level. Two complementary layers.

What's the actual auto-renewal price for Kaspersky Premium in 2026?

Outside the U.S.: Kaspersky Premium first-year promotional is $49.99 (5 devices); renewal jumps to roughly $79.99 the same coverage. Kaspersky Standard first-year $29.99, renewal $49.99. Cancel auto-renew on day one in My Kaspersky → Subscriptions → Auto-Renewal Off. The lapse-and-repurchase tactic — cancel, let the licence expire, repurchase as a new customer through the public site — saves roughly $20-30 per year. Kaspersky also grants retention discounts on phone calls if you mention new-customer pricing. (U.S. customers were auto-migrated to UltraAV in September 2024 and have separate billing.)

What is Kaspersky System Watcher and do I need it?

System Watcher is Kaspersky's behavioural-rollback engine, included with all paid tiers. It tracks application behaviour patterns over time and rolls back malicious changes if ransomware activity is detected mid-execution — for example, if an unknown executable starts encrypting files in Documents, System Watcher kills the process and restores the encrypted files from a temporary shadow store. Worth keeping ON. The trade-off: System Watcher uses 30-80 MB of additional RAM for the rollback buffer. On systems with 8 GB or more RAM, the cost is negligible.

Final Verdict — Is Kaspersky Worth It?

U.S. users: no — not an option. The September 29, 2024 U.S. Department of Commerce Final Determination prohibits Kaspersky from providing services or updates to U.S. customers; existing installations were migrated to UltraAV automatically. See the banner at the top of this page. Switch to Bitdefender (the closest detection-and-features match), Norton (if you want LifeLock identity protection bundled), or ESET (if you want a non-Gen-Digital paid alternative with strong corporate transparency). Users outside the U.S. and German federal jurisdiction: yes, on technical merit alone. Kaspersky Premium at $49.99 first year for up to 20 devices wins more AV-Comparatives 2025 awards than any other consumer product — double Gold (Malware Protection, Low False Positives) plus Silver (Advanced Threat Protection). For users whose primary criterion is lab-tested detection rate and whose threat model accepts the Russia-origin geopolitical risk, Kaspersky is the technically correct pick in May 2026.

Users outside the U.S. and Germany (federal): yes, on technical merit. Kaspersky Premium at $49.99 first year wins more AV-Comparatives 2025 awards than any other consumer product — Gold in both Malware Protection and Low False Positives, plus Silver in Advanced Threat Protection. For users whose primary criterion is lab-tested detection, this is the correct pick.

Users in Germany: yes for private use, no for federal contexts. BSI advisory does not affect private consumers but is relevant for federal employees.

Users sensitive to corporate origin: no. The Swiss data-processing relocation is meaningful but does not change the founder's and historical corporate origin. ESET (Slovak, independent) or Bitdefender (Romanian, independent) are cleaner options.

For the 2026 lineup of top-rated consumer antivirus products (outside the U.S.), Kaspersky Premium is our #6 overall pick — demoted from top-5 solely because the U.S. restriction eliminates it for a large portion of our readership. On pure detection quality, this is arguably the #1 product of 2025-2026.
