Bitdefender vs. Kaspersky: Why This Isn't a Real Comparison for US Users
A side-by-side feature comparison between Bitdefender and Kaspersky isn't actually useful for US readers, because it isn't a real choice anymore: in 2024, the US Department of Commerce banned the sale of Kaspersky antivirus software in the United States, citing national security concerns tied to the company's Russian ownership. Kaspersky is no longer sold to US customers, and existing US installations stopped receiving updates — meaning any copy still running in the US is not being maintained and shouldn't be relied on for protection. This isn't a reflection of Kaspersky's historical lab performance (it has, at various points, scored well in independent testing) — it's a US regulatory action that makes the product unavailable and unsupported here, regardless of its technical merits.
What This Means for US Readers
If you or someone you know is still running Kaspersky software in the US, the practical guidance is straightforward: switch to an actively maintained, currently available antivirus product. An antivirus that no longer receives updates can't protect against newly discovered threats, which defeats its purpose.
Bitdefender as an Alternative
Bitdefender has a strong, long-standing reputation in independent lab testing (AV-TEST, AV-Comparatives) and offers a full range of tiers, from a base antivirus plan up through Total Security, which bundles in a VPN, password manager, and other tools. See our full Bitdefender Total Security review for a detailed look at what the suite includes and what to watch for (particularly around renewal pricing, which jumps significantly after the introductory term — a common pattern across the antivirus industry, not specific to Bitdefender).
Other Well-Regarded Alternatives
Beyond Bitdefender, several other established antivirus providers are commonly recommended and consistently score well in independent testing, including Norton, ESET, and Microsoft Defender (built into Windows, and a genuinely solid baseline option for many users). The right choice among these depends on which extra features (VPN, parental controls, identity protection) matter to you — see our broader antivirus guides for more detailed comparisons among currently available options.
Frequently Asked Questions
Can I still use Kaspersky in the US? No — the US Department of Commerce banned the sale of Kaspersky software in 2024, and existing installations no longer receive updates. Switch to an actively maintained alternative. Is this because Kaspersky's antivirus engine is technically weak? No — this is a US regulatory action based on national security concerns related to Kaspersky's Russian ownership, not a technical performance issue. What's a good Kaspersky alternative? Bitdefender, Norton, ESET, and Microsoft Defender are all actively maintained, well-regarded options currently available to US consumers.
The Bottom Line
This isn't really a "which is better" comparison anymore — Kaspersky isn't a legally available, actively updated option for US consumers, so the practical answer is to choose from currently available alternatives like Bitdefender, Norton, ESET, or Microsoft Defender based on which extra features you need. See our Bitdefender Total Security review for a deeper look at one of the strongest current options.
