Which is better, Kaspersky or Bitdefender? For U.S. readers, Bitdefender is the practical choice between these two because U.S. restrictions block Kaspersky antivirus updates. Elsewhere, recent independent lab tests show no consistent overall winner: the products tied in one Windows 11 test, while Kaspersky had a slight edge in one malware-protection test. Compare the specific local plans, renewal costs, device coverage, and features you would actually use.
Which antivirus has better protection?
Recent independent tests show strong results for both products, but they measure different things. No single result establishes which antivirus is safer for every user, platform, or country.
AV-TEST: a tie on Windows 11
In AV-TEST’s August 2026 Windows 11 home-user round, Bitdefender Total Security 27.0 and Kaspersky Premium 21.24/21.25 each scored 6/6 in protection, 6/6 in performance, and 6/6 in usability—18/18 overall. AV-TEST evaluated products during July and August using default settings, current publicly available versions, updates, and cloud services. Its maximum is 18 points; 17.5 or more earns a “TOP PRODUCT” award. This is a tie for that test cycle, not a verdict across all platforms or circumstances. AV-TEST results

AV-Comparatives’ March 2026 Windows Malware Protection Test used 10,000 test cases and allowed updates and cloud connectivity. Bitdefender recorded 97.6% offline detection, 97.6% online detection, 99.94% online protection, and four false alarms. Kaspersky recorded 92.1% offline detection, 97.8% online detection, 99.97% online protection, and two false alarms. The online-protection difference was small in this test; the detection figures describe distinct stages and should not be treated as interchangeable. False alarms also matter because they can disrupt users and affect how detection results are interpreted. AV-Comparatives test details

Annual awards split by category
In AV-Comparatives’ 2025 consumer awards, both products were Top-Rated Products. Bitdefender earned silver for real-world protection, bronze for malware protection, gold for optional advanced threat protection, and bronze for false positives. Kaspersky earned bronze for real-world protection, gold for malware protection, silver for optional advanced threat protection, and gold for false positives. The split is another reason to consider the protection situations and trade-offs that matter to you, rather than relying on a single overall rank. AV-Comparatives 2025 awards
AV-Comparatives advises considering other recent tests alongside price, ease of use, compatibility, and support. Test results describe the tested products and conditions; they do not predict every individual outcome.
Is Kaspersky still available in the US?
Kaspersky’s U.S. availability is constrained by a U.S. Department of Commerce prohibition. Covered new agreements with U.S. persons have been prohibited since July 20, 2024. Beginning September 29, 2024, Kaspersky was prohibited from providing relevant antivirus signature and codebase updates or operating Kaspersky Security Network in the United States or on a U.S. person’s system. The rules also prohibit specified resale, integration, and licensing transactions. Bureau of Industry and Security determination
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteThe agency’s action is an availability and update-continuity constraint, not a comparative antivirus test. BIS said continued use of existing products would not itself expose individuals or businesses to legal penalties under the determination, while encouraging U.S. users and businesses to transition to other vendors. For someone in the United States choosing a currently supported consumer antivirus between these two, Bitdefender is the practical option.

Which one is better value?
Value depends on your country and the exact subscription being offered. The official Bitdefender U.S. consumer page lists Total Security and higher tiers, with individual and family options and different device and account allowances. The listed dollar amounts are vendor-page offers, not a complete long-term cost comparison; check the billing period, renewal price, taxes, and device limit at checkout. Bitdefender U.S. consumer plans
Kaspersky’s consumer pages list Standard Antivirus, Plus Internet Security, and Premium Total Security. Its Premium page lists antivirus, unlimited VPN, a password manager and vault, premium 24/7 remote IT support, and compatibility with Windows, macOS, Android, iOS, and Linux. Availability and terms depend on region. Kaspersky Premium features
These published details do not amount to a complete plan-for-plan comparison. Before deciding, compare the exact local tiers and subscription terms rather than assuming similarly named plans include the same tools or cover the same number of devices.

Is Kaspersky better than Bitdefender?
There is no universal winner supported by these tests. The AV-TEST Windows 11 round was tied, and AV-Comparatives’ March 2026 malware test showed a very small online-protection advantage for Kaspersky alongside fewer false alarms in that specific test. The 2025 awards also varied by category. Outside the United States, choose based on the current local offer, supported devices, renewal cost, included tools, support, and your trust or jurisdiction requirements. In the United States, the update restrictions make Bitdefender the practical choice between the two.
