Compare Eset vs Kaspersky
ESET vs Kaspersky at a Glance
US users — read this first: the U.S. Department of Commerce banned new Kaspersky sales and updates in the United States effective September 29, 2024. Existing installs were redirected to UltraAV (an Arizona-based replacement) or uninstalled. If you are in the US, Kaspersky is not a legal option in 2026. Pick ESET outright, or see our 2026 ranking for alternatives.
This is the most interesting head-to-head on pure detection in consumer security. ESET Home Security Ultimate and Kaspersky Premium are the two remaining top-tier independent antivirus brands — neither is part of the Gen Digital consolidation (Norton, Avast, AVG, Avira, LifeLock), neither is owned by McAfee, and both are run from non-US headquarters (Slovakia and Russia respectively). Both hit top-tier at AV-TEST February 2026 and share Gold awards at the AV-Comparatives 2025 Summary Report. The difference is where they can be sold, what they bundle, and what compliance footprint each carries.
Headline verdict: Kaspersky wins on pure detection (18/18 AV-TEST + double Gold at AV-Comparatives 2025: Malware Protection and Low False Positives). ESET wins everywhere it matters for most readers: legal to buy everywhere in the world, lightest system impact of any premium suite, same price tier, Gold Advanced Threat Protection. For non-US readers, Kaspersky is a legitimate pick if you want the single best pure-detection engine. For US readers, ESET is the only option of the two.
Quick Verdict Table
| ESET Home Security Ultimate | Kaspersky Premium | |
|---|---|---|
| First-year price (5 devices) | $49.99 | $49.99 |
| Availability | Worldwide | Banned in US (Sep 2024) |
| AV-TEST Feb 2026 | 17.5 / 18 | 18 / 18 |
| AV-Comparatives 2025 top award | Gold Advanced Threat Protection | Gold Malware Protection + Gold Low FP |
| System impact (full scan CPU) | 6-22% | 15-30% |
| Corporate HQ | Bratislava, Slovakia (EU) | Moscow, Russia |
| Founded | 1992 | 1997 |
| Key strength | Lightest on system + global legality | Best pure detection engine |
Both are $49.99 first year. Both are independent (not Gen Digital, not McAfee). The decision turns on geography (US users must pick ESET) and on whether you prioritize absolute-lowest system impact (ESET) or absolute-highest detection rate (Kaspersky).
Lab Test Showdown
AV-TEST February 2026 (Windows 11 Home User cycle):
- Kaspersky Premium: 18 / 18 (Protection 6/6, Performance 6/6, Usability 6/6). Top Product.
- ESET Home Security Ultimate: 17.5 / 18 — lost half a point on Usability (false-positive handling). Still Top Product.
AV-Comparatives 2025 Summary Report:
- Malware Protection Test: Kaspersky Gold (highest detection rate on the 10,000+ sample corpus, tied with Bitdefender). ESET Silver.
- Low False Positives: Kaspersky Gold (fewest FPs across the year). ESET Silver.
- Advanced Threat Protection: ESET Gold (tied with Bitdefender, ahead of Kaspersky Silver). This is the hardest category — multi-stage targeted attacks with living-off-the-land binaries.
- Real-World Protection: Kaspersky Silver, ESET Silver (both behind Norton Gold).
- Performance: ESET Silver, Kaspersky Silver.
What this means: Kaspersky has the edge on pure signature detection and false-positive discipline. ESET has the edge on the hardest category (defending against sophisticated targeted attacks with fileless techniques). Both are elite; neither has a "missed a major threat" record.
Pricing + Renewal Reality
First-year pricing (5 devices, top tier):
- ESET Home Security Ultimate: $49.99. Internet Security (mid tier) $39.99; base tier $29.99.
- Kaspersky Premium: $49.99 (where legally available). Kaspersky Plus (mid tier) $39.99; Kaspersky Standard $29.99.
Identical top-tier pricing structure. Both are more expensive than Bitdefender Total Security ($19.99) and Norton 360 Deluxe ($49.99) at the first-year entry point — you pay for detection depth, not bundle size.
Renewal pricing:
- ESET: auto-renewal around $89.99-$99.99 depending on tier. No systematic renewal-complaint pattern.
- Kaspersky: auto-renewal around $94.99 (non-US markets). No systematic renewal-complaint pattern.
Both are cleaner on renewal than Norton or TotalAV. Both cancel straightforwardly through account portals.

Feature parity is close. ESET has the edge for power users on HIPS (Host Intrusion Prevention System) depth — the rules engine is more exposed to advanced configuration than Kaspersky's. Kaspersky has the edge on Safe Money's isolated-banking browser implementation, which is widely considered the strongest in the category.

ESET is the single lightest premium antivirus suite we test. The gap vs Kaspersky is real but narrow; the gap vs Norton or McAfee is substantial. If you run older hardware, a gaming rig, a development laptop, or anywhere CPU cycles matter, ESET is the right pick in this matchup even before the availability question.
Who Should Pick ESET
- US users. Kaspersky is banned by the U.S. Department of Commerce effective September 29, 2024. ESET is the only legal pick of these two in the United States.
- Users on older or lighter hardware. 6-22% CPU during full scans and 95-120 MB idle RAM — the lightest of the premium suites. Pre-2020 laptops, Chromebooks running Windows, older gaming rigs: ESET is the category winner.
- Gamers and creators who need low background overhead. Gamer Mode suspends notifications and throttles background scans during full-screen applications. HIPS depth lets power users tune rules without fighting the product.
- Users who want maximum protection against targeted / sophisticated attacks. Gold at AV-Comparatives 2025 Advanced Threat Protection — the category measuring defense against fileless techniques and living-off-the-land binaries.
- Users who prefer EU-headquartered, independent ownership. Slovakia-based, privately held, founded 1992. Not part of Gen Digital. Not under US CFIUS concerns.
- Users who travel internationally. ESET is legal worldwide, which avoids the license-transfer complications Kaspersky users hit when moving residences across jurisdictions.
Who Should Pick Kaspersky (Non-US Only)
- Non-US users who want the best pure-detection engine on the market. 18/18 AV-TEST + Gold Malware Protection + Gold Low False Positives at AV-Comparatives 2025. No other consumer product has that combination in a single year.
- Online banking heavy users (non-US). Safe Money's isolated-banking browser is widely considered the strongest implementation in the category, with verified-SSL enforcement and on-screen keyboard protection against keyloggers.
- Users who want aggressive ransomware rollback. System Watcher can reverse encryption operations up to a configurable file-size limit, with notably deeper rollback history than most competitors.
- Users comfortable with the corporate footprint. Kaspersky is a Russia-headquartered private company. Global-transparency efforts include the Kaspersky Transparency Initiative with data processing moved to Zurich. The US ban is a compliance decision, not a product-quality decision — but for users who do not want that corporate footprint on their machine, ESET is the equivalent-quality alternative.
We note: do not buy Kaspersky if you are in the US. The ban means no updates, no support, eventual migration. Full Kaspersky review.
Frequently Asked Questions
Is Kaspersky banned in the US?
Yes, since September 29, 2024. The U.S. Department of Commerce Final Determination (June 2024) prohibited Kaspersky Lab from providing antivirus software or cybersecurity services in the United States, citing national-security concerns about Russian government access. New sales were blocked after July 20, 2024; software updates and signature delivery stopped September 29, 2024. US customers were migrated to UltraAV or prompted to uninstall. The ban does not apply to users outside the US; Kaspersky Premium remains legitimately available in Europe, the UK, Canada, Asia, and Australia.
Is ESET better than Kaspersky?
Tied at the top, with different strengths. Kaspersky has the edge on pure detection (18/18 AV-TEST + double Gold at AV-Comparatives 2025). ESET has the edge on Advanced Threat Protection (Gold at AV-Comparatives), system impact (lightest premium suite), and global availability (legal worldwide, Kaspersky banned in US). For most readers, ESET is the practical winner because it is available everywhere and runs lighter. For non-US users prioritizing pure detection, Kaspersky is the detection-optimal pick.
Can I run ESET and Kaspersky together?
No. Two real-time antivirus engines will fight each other, disable services, and leave you less protected than either alone. Pick one. Windows automatically disables Microsoft Defender when you install either product. Malwarebytes Premium is the only exception to this rule — it is engineered to run alongside another real-time product.
Which is lighter on system resources, ESET or Kaspersky?
ESET, by a clear margin. In hands-on testing ESET peaked at 6-22% CPU during full scans with 95-120 MB idle RAM. Kaspersky peaked at 15-30% CPU with 140-180 MB idle RAM. Both are lighter than Norton or McAfee. If your hardware is pre-2020 or you run CPU-intensive workloads, ESET is the right pick. On modern hardware the difference is imperceptible.
Is Kaspersky safe to use outside the US?
Yes, and it is one of the best pure-detection engines in consumer security. The US ban is a compliance decision based on US national-security policy toward Russian companies; it is not a finding that the product leaks data or fails to protect. Kaspersky has run the Global Transparency Initiative since 2018, moved data processing infrastructure to Zurich, and opened source-code reviews to external auditors. For non-US users the product is fully supported and detection-leading. For US users, the legal alternative is ESET.
Do ESET and Kaspersky include VPNs?
Yes, on the top tiers. ESET Home Security Ultimate and Kaspersky Premium both include unlimited VPN service. Lower tiers (ESET Internet Security, Kaspersky Plus) include limited-data VPN. Neither VPN matches the throughput or server network of standalone services like ExpressVPN or Mullvad, but both are adequate for normal browsing and public Wi-Fi protection.
Final Verdict: the One-Line Answer
Pick ESET Home Security Ultimate for 2026 unless you are a non-US user who specifically wants the single best pure-detection engine on the market — in which case pick Kaspersky Premium. ESET wins on availability (legal worldwide), system impact (lightest premium suite), and Advanced Threat Protection Gold. Kaspersky wins on pure detection (Gold Malware + Gold Low FP) but is US-banned. For US readers, ESET is the only option. For non-US readers, the decision turns on what you prioritize.
