Compare Bitdefender vs Kaspersky
Bitdefender vs Kaspersky at a Glance
US readers, read this first. The U.S. Department of Commerce banned new Kaspersky sales and software updates in the United States effective September 29, 2024. Existing US Kaspersky customers were migrated to UltraAV (an Arizona-based replacement) or prompted to uninstall. If you are in the US, do not buy Kaspersky — pick Bitdefender Total Security and move on. The rest of this comparison applies to readers in Europe, the UK, Canada, Asia, Australia, and other markets where Kaspersky remains legitimate to buy.
Outside the US, this is the most interesting matchup in consumer security. Both products scored 18/18 at AV-TEST February 2026. At the AV-Comparatives 2025 Summary Report, Kaspersky took double Gold — Gold for Malware Protection and Gold for Low False Positives. Bitdefender took Gold for Advanced Threat Protection. Kaspersky has the lab-best pure-detection record of any consumer product in 2025; Bitdefender has the stronger overall bundle and is legitimately available everywhere.
Headline verdict (non-US): Kaspersky Premium wins on raw detection and false-positive rate. Bitdefender Total Security wins on price, system impact, and bundle. For US users, only Bitdefender is a legitimate choice.
Quick Verdict Table
| Bitdefender Total Security | Kaspersky Premium | |
|---|---|---|
| First-year price (5 devices) | $19.99 | $49.99 |
| Renewal price | $89.99 | $99.99 |
| AV-TEST Feb 2026 | 18 / 18 | 18 / 18 |
| AV-Comparatives 2025 top award | Gold Advanced Threat Protection | Gold Malware Protection + Gold Low FP |
| System impact (full scan CPU) | 20-35% | 18-30% |
| US availability | Yes | No (banned Sept 2024) |
| Key differentiator | Best value everywhere | Lab-best detection (non-US) |
Kaspersky's Gold in both Malware Protection and Low False Positives at AV-Comparatives 2025 is a genuinely rare result — no consumer product has taken both top awards in one year since 2019. The detection engine is the best on the market by lab metrics. The caveats are the US ban and the geopolitical baggage.
Lab Test Showdown
AV-TEST February 2026: both scored 18 / 18. Protection 6/6, Performance 6/6, Usability 6/6 across the board. Top Product designation for both.
AV-Comparatives 2025 Summary Report:
- Malware Protection Test: Kaspersky Gold (99.99% detection), Bitdefender Advanced+ (no medal). Kaspersky detected more samples than any other consumer product across the full-year test.
- False Positives: Kaspersky Gold for lowest FP rate — under 2 false positives across 1,000+ clean samples. Bitdefender had 1 FP (also excellent, but Kaspersky's consistency across the year earned the medal).
- Advanced Threat Protection: Bitdefender Gold; Kaspersky Silver. On multi-stage targeted attacks Bitdefender's behavioral engine edges Kaspersky.
- Real-World Protection: Kaspersky Silver, Bitdefender Silver. Tied in this category.
- Performance Test: Kaspersky Advanced+ (no medal, near the top of the field), Bitdefender Silver.
What this means: if your goal is the lowest possible miss rate on commodity malware and the lowest possible false-positive rate on legitimate software, Kaspersky is measurably the best product on the market. Bitdefender's strength is targeted and novel threats (the Advanced Threat Protection Gold). For 95% of users browsing normal websites, either product catches what you encounter — but Kaspersky's lab record is the most consistent.
Pricing + Renewal Reality
First-year pricing:
- Bitdefender Total Security: $19.99 for 5 devices.
- Kaspersky Premium: $49.99 for 5 devices.
Bitdefender is less than half the price out of the gate. Kaspersky's pricing matches the ESET/Norton tier but lacks the LifeLock bundle that justifies Norton's price.
Renewal pricing:
- Bitdefender Total Security: $89.99. Lowest in the premium tier.
- Kaspersky Premium: $99.99. Moderate; no extreme renewal inflation like Norton.
Two-year math: Bitdefender runs about $110 over two years; Kaspersky about $150. The $40 gap is real but not as dramatic as Bitdefender vs McAfee or Bitdefender vs Norton over the same window.
US-specific pricing note: Kaspersky is not sold in the US, period. If you are in the US and a site is offering Kaspersky, the seller is either shipping international (grey-market) or selling UltraAV rebranded as Kaspersky — neither of which is the actual Kaspersky product with active Russian-lab signature updates.

Kaspersky Premium wins on bundle: unlimited VPN, Safe Money (the best safe-banking implementation in consumer security), and remote IT support are all included. Bitdefender wins on price and overall system impact. The feature sets are the closest of any matchup in this comparison series.
Real-World Performance
Both products tested on the same mid-range Windows 11 laptop (Intel i5-12450H, 16 GB DDR5, NVMe SSD).
| Metric | Bitdefender | Kaspersky |
|---|---|---|
| Idle RAM | 140 MB | 150-180 MB |
| Full scan CPU peak | 20-35% | 18-30% |
| Full scan time (280 GB) | 18 minutes | 16 minutes |
| Boot delta vs clean | +2 seconds | +2-3 seconds |
| Background processes | 3 | 3-4 |
| VPN throughput (500 Mbps line) | 220-310 Mbps (capped) | 210-290 Mbps (unlimited) |
Kaspersky's scan engine is actually slightly faster and slightly lighter on peak CPU than Bitdefender — this is one area where the Kaspersky Lab engineering shows through. Both products are in the light tier; the difference is academic on modern hardware.
Who Should Pick Bitdefender
- US users. Kaspersky is not legally sold in the US since September 2024. Bitdefender is the clear pick.
- Price-conscious buyers worldwide. $19.99 first year vs $49.99. More than half the price.
- Users worried about geopolitical supply-chain risk. Kaspersky is a Russian-origin company with a legitimate (but scrutinized) Swiss transparency-centers program. If your threat model or compliance requirements preclude Russian-origin software, Bitdefender (Romania) is the alternative.
- Users wanting Gold for Advanced Threat Protection. Bitdefender's behavioral engine took Gold at AV-Comparatives 2025; Kaspersky was one tier below on the same test.
- Anyone buying business / compliance software. Many enterprise and government-contractor environments exclude Kaspersky by policy regardless of geography. Bitdefender has no such restrictions.

Who Should Pick Kaspersky (Non-US Only)
- Users who want the lab-best detection engine money can buy. Gold in Malware Protection and Gold in Low False Positives at AV-Comparatives 2025 is the most consistent lab record of any consumer product. If detection quality is your only priority, Kaspersky is the answer.
- Users who do a lot of online banking. Kaspersky's Safe Money is the most complete safe-banking implementation in consumer security — automatic detection of banking sites, hardened virtualized browser session, screenshot-blocking, keylog protection. Bitdefender Safepay is good; Safe Money is better.
- Users who want remote IT support bundled. Kaspersky Premium includes remote IT support sessions — a real human can connect to your machine and help with config. Bitdefender does not offer this in the base tier.
- Users outside the US who want unlimited VPN bundled. Kaspersky's unlimited VPN at the Premium tier matches Norton's bundle without the LifeLock US-only constraint.
- Users who prioritize low false positives. If you run unusual software, custom scripts, or compiled developer tools, Kaspersky's Gold for Low FP means fewer wrongful quarantines.

Frequently Asked Questions
Why is Kaspersky banned in the US?
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, 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. The ban does not apply to users outside the US; Kaspersky Premium remains available and legitimate in Europe, the UK, Canada, Asia, and Australia.
Which is better, Bitdefender or Kaspersky, for detection?
Kaspersky by the numbers. Both scored 18/18 at AV-TEST Feb 2026, but AV-Comparatives 2025 awarded Kaspersky Gold for Malware Protection and Gold for Low False Positives — the only consumer product to take both in 2025. Bitdefender took Gold for Advanced Threat Protection (a different test measuring targeted attacks). For commodity malware, Kaspersky has the edge. For fileless and multi-stage attacks, Bitdefender does.
Is Kaspersky safe to use?
Outside the US, yes — Kaspersky remains one of the most tested and certified consumer antivirus engines on the market, with transparency centers in Switzerland (source-code review) and Madrid. There are no documented incidents of malicious Kaspersky behavior against consumer users in 2024-2026. Inside the US, the software cannot receive signature updates since September 2024, which makes it unsafe to use regardless of the geopolitical question. US users should switch to Bitdefender, Norton, or ESET.
Is Bitdefender from a safer country than Kaspersky?
Bitdefender is Romanian-origin (EU, NATO member). Kaspersky is Russian-origin. For users whose compliance or personal threat model excludes Russian-origin software, Bitdefender is the correct pick. For users who trust the Swiss transparency program and the independent audits, Kaspersky's engineering is genuinely top-tier. The geopolitical question is personal; the lab results are objective.
Does Kaspersky have a better VPN than Bitdefender?
Kaspersky Premium includes unlimited VPN at the base tier. Bitdefender Total Security caps at 200 MB/day and charges $30/year extra for unlimited. If you will use a VPN regularly, Kaspersky's bundle is better out of the box.
Should I install Kaspersky if I already installed UltraAV?
If you are in the US, no — you should not install Kaspersky. UltraAV is a US-based Arizona company that took over the US Kaspersky customer base after the September 2024 ban; it is not Kaspersky and does not use the Kaspersky engine. If you are in the US, uninstall UltraAV if you do not want it and install Bitdefender, Norton, or ESET instead.
Final Verdict: the One-Line Answer
If you are in the US: pick Bitdefender Total Security. Kaspersky is not a legal option.
If you are outside the US and want the lab-best detection engine: pick Kaspersky Premium. Gold for Malware Protection and Gold for Low False Positives at AV-Comparatives 2025 is the cleanest lab record in consumer security.
If you are outside the US and want the best value: pick Bitdefender Total Security. Half the price, equivalent detection for the threats most users actually face, independent Romanian origin.
