Compare Kaspersky vs Malwarebytes
Kaspersky vs Malwarebytes at a Glance
US users - important: the U.S. Department of Commerce banned new Kaspersky sales and updates in the United States effective September 29, 2024. If you are in the US you cannot legally purchase Kaspersky Premium; existing installs were migrated to UltraAV or prompted to uninstall. For US readers this comparison effectively resolves to "install Malwarebytes on top of Microsoft Defender." For readers outside the US (UK, EU, Canada, Asia, Australia), both products remain available and legitimate.
Kaspersky Premium is the best pure-detection antivirus engine in consumer security: 18 / 18 at AV-TEST February 2026 and double Gold at the AV-Comparatives 2025 Summary Report (Gold Malware Protection and Gold Low False-Positives). No other consumer product took two Golds from AV-Comparatives 2025. Malwarebytes Premium is the best second-layer product, named AVLab Product of the Year 2026, designed to run alongside another real-time engine and catch what signatures missed.
Headline verdict: these are not direct competitors — Kaspersky is a full primary antivirus, Malwarebytes is a specialist second layer. Outside the US: pick Kaspersky Premium as your primary AV if pure detection is your priority; add Malwarebytes as a second layer if you want post-compromise cleanup and exploit mitigation. Inside the US: Kaspersky is not available; install Malwarebytes Premium on top of Microsoft Defender as the community-standard replacement stack.

Lab Test Showdown
Kaspersky Premium — AV-TEST February 2026: 18 / 18 (Protection 6/6, Performance 6/6, Usability 6/6). Top Product. Kaspersky has maintained 18/18 every cycle since 2018 — the longest unbroken perfect streak in the industry.
Kaspersky Premium — AV-Comparatives 2025 Summary Report:
- Malware Protection Test: Gold (99.99% detection on 10,000+ samples, zero misses in the top-10 threat families).
- Low False-Positives: Gold (only 1 false positive across 1,000+ clean samples — the best of any product tested).
- Real-World Protection: Silver (98.9% block rate, behind Norton's Gold).
- Performance: Silver.
Double Gold at AV-Comparatives 2025 is the statement. No other consumer AV took two Gold awards in the 2025 cycle.
Malwarebytes Premium — AVLab Product of the Year 2026: standout scores on Advanced In-the-Wild Malware Protection and Fileless Attack Detection. AVLab tests the specific categories where second-layer products prove their value: post-compromise persistence, exploit-kit blocking, and novel-technique detection. Malwarebytes does not submit to most AV-TEST or AV-Comparatives flagship tests because its product is not designed to compete on generic-AV methodology.
What this means: on primary real-time AV Kaspersky is at the top. On specialist second-layer cleanup Malwarebytes is at the top. Comparing them against each other on a single metric misses the point. The right pairing, outside the US, is both products layered. Inside the US, Kaspersky is not an option.
Pricing + Renewal Reality
Kaspersky Premium: $49.99 first year for 5 devices (intro pricing, typical for first year). Renewal is $104.99 on auto-renew — similar to Norton's renewal pattern. Kaspersky's retention pricing and email-discount offers are generally easier to negotiate than Norton's.
Malwarebytes Premium: $44.99 first year for 5 devices, often $34.99-$39.99 on sale. Renewal is close to intro — Malwarebytes has the most honest renewal pricing in consumer security. You do not need to manage renewal actively.
Combined layered stack (non-US): Kaspersky Premium + Malwarebytes Premium = ~$95 first year. Both products deliver what they promise; the combined cost is still less than buying each a la carte ($50 + $45 = $95) with no bundling discount. For maximum paranoia-grade protection outside the US, this is the premium tier.
Replacement stack (US): Microsoft Defender (free) + Malwarebytes Premium ($44.99) = $44.99/year. The Defender + Malwarebytes combination is the community-standard US replacement for users who previously relied on Kaspersky and need to migrate off.

Kaspersky Premium is a full-featured consumer suite — it bundles everything Norton bundles (VPN, password manager, parental controls) plus the Safe Money isolated browser, which is uniquely good for online banking. Malwarebytes is deliberately narrow: real-time threat blocking, exploit mitigation, ransomware rollback, PUP/adware removal. No VPN, no password manager, no parental controls. Different products for different jobs.
Real-World Performance
We ran both on the same mid-range Windows 11 laptop (Intel i5-12450H, 16 GB DDR5, NVMe SSD) for a week each.
| Metric | Kaspersky Premium | Malwarebytes Premium (alone) |
|---|---|---|
| Idle RAM | 150-180 MB | 80-120 MB |
| Full scan CPU peak | 25-38% | 20-30% |
| Full scan time (280 GB) | 19 minutes | 15 minutes (targeted, not exhaustive) |
| Boot delta vs clean | +3-4 seconds | +1-2 seconds |
| Background processes | 3-4 | 2 |
| VPN throughput (500 Mbps line) | 210-300 Mbps (unlimited) | n/a (add-on) |
Both are genuinely light — Malwarebytes lighter because it is not a full-scope AV. Kaspersky's Safe Money browser launches as an isolated environment for banking sessions, which adds a one-time 2-3 second launch delay but isolates the session from keyloggers and screen-capture malware — a feature nobody else in this comparison matches at the consumer tier.
Who Should Pick Kaspersky (Non-US Only)
- Non-US users who want best-in-class primary detection. Double Gold at AV-Comparatives 2025 is the strongest lab result of any consumer product. If detection is your #1 criterion and you are in Europe, UK, Canada, Asia, Australia, or elsewhere outside the US, Kaspersky is the right pick.
- Heavy online-banking users. Safe Money isolated browser is uniquely strong for online banking sessions. No other consumer AV offers an equivalent banking-browser at this level of polish.
- Parents who want robust parental controls. Kaspersky Safe Kids is included in Premium and is one of the strongest parental-controls implementations in consumer security.
- Users who want the full bundle with unlimited VPN. Kaspersky Premium bundles unlimited VPN (Kaspersky Secure Connection), password manager, and identity-theft monitoring at a single price.
- Linux users. Kaspersky Internet Security for Linux is a rare consumer Linux AV; the Premium Windows product shares the same engine. For mixed-OS households, Kaspersky is one of the few cross-platform picks.

Who Should Pick Malwarebytes (US and Non-US)
- US users who previously used Kaspersky. Kaspersky is banned in the US as of September 29, 2024. If you are migrating off Kaspersky, the community-standard replacement is Microsoft Defender + Malwarebytes Premium — the closest equivalent stack available to US consumers.
- Anyone wanting a second layer on top of any primary AV. Malwarebytes is engineered to run alongside Defender, Norton, Bitdefender, ESET, or any other real-time engine without conflicts.
- Users who download freeware or install software from third-party sites regularly. PUP and adware bundlers are Malwarebytes' specialty.
- Households with users who click unpredictable things. Parents, grandparents, kids. Malwarebytes' exploit mitigation and web protection catches what a primary AV misses.
- Anyone who has been infected before. The 7-day ransomware rollback and behavioral anomaly detection are exactly the features you need after a narrow escape.
- Small-business users on Windows 11 Home. Malwarebytes Anti-Exploit fills the exploit-mitigation gap between consumer Defender and enterprise Microsoft Defender for Endpoint.

Frequently Asked Questions
Is Kaspersky banned in the US?
Yes. The U.S. Department of Commerce issued a Final Determination in June 2024 prohibiting Kaspersky Lab from providing antivirus software or cybersecurity services in the United States. New sales were blocked after July 20, 2024; software updates and signature delivery stopped September 29, 2024. US customers were migrated to UltraAV (an Arizona-based replacement) or prompted to uninstall Kaspersky entirely. The ban does not apply outside the US; Kaspersky Premium remains available and legitimate to buy in Europe, the UK, Canada, Asia, and Australia.
What should US users install instead of Kaspersky?
The community-standard replacement is Microsoft Defender (on by default, free, 18/18 at AV-TEST) plus Malwarebytes Premium ($44.99/year for 5 devices) layered on top. This combination replicates much of what Kaspersky Premium offered US users — strong real-time AV plus specialist second-layer cleanup — at half the cost. If you want the bundled-features part Kaspersky offered (VPN, password manager, parental controls), step up to Norton 360 Deluxe or Bitdefender Total Security instead.
Can I run Kaspersky and Malwarebytes together?
Yes. Malwarebytes Premium is engineered to run alongside any primary real-time antivirus engine, including Kaspersky. Windows will not disable Kaspersky when Malwarebytes installs, and Malwarebytes does not conflict with Kaspersky's real-time scanner because it targets a narrower threat category (PUPs, exploits, ransomware rollback, post-compromise cleanup). This is the same layered model we recommend with Microsoft Defender + Malwarebytes — just with a premium primary AV instead of the Windows baseline.
Is Kaspersky safe to use outside the US?
That is a policy and risk-tolerance question, not a technical one. Technically, the Kaspersky engine has been one of the top three consumer detection products every year since 2012, and independent labs have never produced evidence of signature or engine compromise. The US ban is based on national-security concerns about Russian government jurisdiction over Kaspersky's corporate structure, not a demonstrated product flaw. For non-government, non-critical-infrastructure home users outside the US, Kaspersky remains widely used and is legitimate to buy. Users with elevated threat models (journalists covering Russia, dissidents, government contractors) may reasonably choose Bitdefender or ESET instead regardless of jurisdiction.
Is Malwarebytes enough on its own?
As a primary antivirus, no — Malwarebytes is explicitly not designed to be your only protection. It does not submit to or compete in the generic real-time AV category at AV-TEST or AV-Comparatives because its product is narrower. Always pair Malwarebytes with a primary real-time AV (Microsoft Defender, Bitdefender, Norton, ESET, or Kaspersky outside the US). Malwarebytes Premium alone, with real-time protection enabled, covers more than Malwarebytes Free alone but still leaves signature-detection gaps that a primary engine fills.
Which is a better second layer: Kaspersky or Malwarebytes?
Wrong question. Kaspersky is not a second layer — it is a full primary antivirus and will conflict with any other real-time AV you install. Malwarebytes is the only top-tier product explicitly engineered to run alongside another real-time engine. If you want a specialist second layer on top of any primary AV, Malwarebytes is the answer. If you want a primary AV, Kaspersky (outside the US) is a top-tier choice.
Final Verdict: the One-Line Answer
Non-US users: pick Kaspersky Premium as your primary AV for best-in-class detection (double Gold at AV-Comparatives 2025), and optionally add Malwarebytes Premium as a second layer for specialist cleanup. US users: Kaspersky is banned and not available — install Malwarebytes Premium on top of Microsoft Defender as the community-standard replacement stack. Neither product replaces the other; they operate at different layers of the protection stack, which is exactly why the layered pairing works.
