It depends first on where you live. In the United States, Kaspersky’s update and service restrictions make Bitdefender the practical choice between these two. Elsewhere, recent independent tests show strong results for both rather than a clear overall winner: they tied in AV-TEST’s August 2026 Windows 11 round, while Kaspersky had a slight edge in one AV-Comparatives malware test. Your best choice depends on local availability, the exact plan, renewal cost, device coverage, and any jurisdiction or organizational requirements.
Which antivirus has better protection?
Recent independent results are close, but they measure different things. AV-TEST’s Windows 11 home-user round in August 2026 gave both products its maximum score. In a separate March 2026 AV-Comparatives malware test, Kaspersky recorded marginally higher online protection and fewer false alarms. Neither result establishes a universal winner for every device, threat, or user.

AV-TEST: a tie in the August 2026 Windows 11 round
AV-TEST evaluated 15 home-user products during July and August 2026, using default settings, current publicly available versions, updates, and cloud services. 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 total. AV-TEST awards its “TOP PRODUCT” distinction at 17.5 points or higher, so both qualified. This is a tie for that Windows 11 test cycle and those versions, not a guarantee of identical results on other platforms or in future tests. See AV-TEST’s Windows home-user results.

AV-Comparatives tested 10,000 cases on Windows with updates and cloud connectivity allowed. The figures below are separate measures: offline detection, online detection, online protection, and false alarms should not be treated as interchangeable scores.

| Product | Offline detection | Online detection | Online protection | False alarms |
|---|---|---|---|---|
| Bitdefender | 97.6% | 97.6% | 99.94% | 4 |
| Kaspersky | 92.1% | 97.8% | 99.97% | 2 |
Kaspersky’s online protection result was 0.03 percentage points higher in this test, with two false alarms versus Bitdefender’s four. Those are small, test-specific differences, not a prediction that one product will protect every user better. False alarms matter because they can disrupt users and complicate interpretation of detection results. Read AV-Comparatives’ March 2026 malware test.
AV-Comparatives: 2025 awards split by category
The annual awards also do not point to a single winner across every protection situation. 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 a reason to consider the kind of protection and trade-offs you value rather than relying on one overall rank. See AV-Comparatives’ consumer awards and results.

Is Kaspersky better than Bitdefender?
Not as a general claim. Kaspersky had a small advantage in online protection and false alarms in the March 2026 AV-Comparatives test, while both products tied at AV-TEST’s maximum score in its August 2026 Windows 11 round. Bitdefender placed higher in AV-Comparatives’ 2025 real-world protection award category; Kaspersky placed higher in malware protection and false positives. These results support a conditional comparison, not a permanent technical verdict. AV-Comparatives recommends looking at other recent tests as well as price, ease of use, compatibility, and support.

U.S. readers should treat the federal prohibition and its effect on updates as the deciding factor before comparing lab scores. The U.S. Department of Commerce’s Bureau of Industry and Security (BIS) prohibited covered new agreements with U.S. persons beginning 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 action also prohibits specified resale, integration, and licensing transactions. Read BIS’s prohibition and scope.

This is a U.S.-specific legal and update-continuity constraint, not a laboratory finding that Kaspersky detects threats less effectively. BIS’s press release says continued use of existing products would not itself expose individuals or businesses to legal penalties under the determination; that does not remove the update restriction. The Department stated its national-security rationale, with Commerce Secretary Gina Raimondo saying: “Russia has shown time and again they have the capability and intent to exploit Russian companies, like Kaspersky Lab, to collect and weaponize sensitive U.S. information, and we will continue to use every tool at our disposal to safeguard U.S. national security and the American people.” This is the agency’s stated rationale, not an independent technical test conclusion. Read the BIS announcement.
For a U.S. reader choosing a currently supported consumer antivirus product between these two, Bitdefender is the practical option. Readers outside the United States should check the rules and availability in their own market; the U.S. restriction should not be generalized to other countries.

Which one is better value?
Value depends on the exact local offer and how much of its coverage and bundled software you will use. The official Bitdefender U.S. consumer page lists Total Security and higher tiers, including individual and family options with different device or account allowances and displayed dollar prices. Those are page-specific offers, not a complete statement of your long-term cost. Check the billing period, renewal price, taxes, device limits, and offer at checkout. Check Bitdefender’s U.S. consumer plans.

These vendor pages do not establish a complete, like-for-like comparison. Before choosing, compare the same market, subscription term, number of devices, operating systems, and support level. A bundle with tools you will not use may be worse value than a simpler plan; a low first-term price does not by itself show the recurring cost.
Quick Recap
What to compare before subscribing
- Availability and updates: confirm the product can be sold and supported where you live, and that security updates will continue.
- Devices and operating systems: match the plan’s simultaneous device allowance and supported platforms to your household or work setup.
- Included tools: count only features you expect to use, such as a VPN, password manager, or remote support.
- Total cost: compare first-term and renewal prices, subscription length, taxes, and any applicable device or account limits.
- Trust requirements: consider your country’s rules and any employer, client, or organizational requirements before installing security software.
How to choose between them
- If you are in the United States: account for the BIS restrictions and update cutoff first. For a currently supported consumer choice between these products, choose Bitdefender.
- If you are elsewhere: use the test results as evidence that both are capable options, not as a substitute for checking local terms and availability.
- Match plans in your region: compare equivalent subscription periods, device counts, supported systems, included tools, and support.
- Check recurring cost and requirements: verify the renewal price and confirm the product meets your personal or organizational trust requirements.
