Is Kaspersky safe to use?
The confusion
The US Commerce Department banned new Kaspersky sales effective September 2024. Germany's BSI issued a warning. But Kaspersky scores at the top of independent detection tests in the same period. The technical data and the regulatory action point in different directions.
Most sources give you either 'it's fine, the ban is political' or 'it's Russian, don't use it' — without explaining why the answer depends on who is asking and what they're using their machine for.
The question is genuinely complicated, and the honest answer has conditions attached.
What most people assume
Most people assume the government bans are backed by technical evidence of a backdoor. They're not — at least not publicly. The US FCC designation and Commerce Department sales ban are based on risk assessment of Kaspersky's potential obligations under Russian law — specifically the SORM legislation requiring Russian companies to facilitate FSB access to data. No documented technical exploitation has been disclosed publicly. 'Not confirmed' is not the same as 'proven safe.'
Most people assume 'no confirmed backdoor' means the product is safe to use without qualification. Antivirus software operates at kernel level — deeper access to your machine than almost any other software running on it. The question isn't only whether Kaspersky has been caught doing something — it's whether granting kernel-level access to a company with documented legal obligations to a foreign intelligence service is a risk worth taking in a given context.
Most people assume the risk is uniform across all users. It isn't. A home user in Southeast Asia browsing news has a different threat model than a European journalist, a US government contractor, or a professional handling sensitive client communications. The advisory landscape distinguishes between consumer and government contexts — the risk isn't the same for everyone.
What's actually true
Kaspersky is technically excellent. Detection rates are consistently among the best in the category across multiple independent test cycles. Performance impact is low. By every technical metric that independent labs measure, it's a top-tier product.
The trust question is not resolvable through performance data alone. Independent labs test detection capability — they don't test whether a company would comply with a government intelligence order. The question of what a company with kernel-level access to your machine would do under legal compulsion from its home country's intelligence services is a structural question that technical testing doesn't address.
Where you might be
If you're a US resident — new Kaspersky purchases are effectively prohibited under the September 2024 Commerce Department ban. The question is resolved by legal constraint, not risk assessment.

If you're outside the US, not covered by a government advisory, and have evaluated the trust framing above — Kaspersky delivers genuinely top-tier detection. The technical performance is real.

If the trust question is unresolved and you'd rather not carry the uncertainty — Bitdefender is the alternative that trades nothing meaningful in protection terms. Romanian company, EU jurisdiction, no government advisories, detection rates that match Kaspersky across long-run test averages.

What no tool solves
No independent security lab tests whether a company would comply with a government intelligence request. AV-TEST and AV-Comparatives measure detection performance and false positive rates — important metrics, but not a measure of company trustworthiness under legal compulsion.
Kaspersky's 2017 relocation of data processing infrastructure to Switzerland and the launch of its Global Transparency Initiative were efforts to address the trust concerns. Whether those measures are sufficient is a judgment call. They don't change the company's legal domicile or its obligations under Russian law.
The answer to 'is Kaspersky safe' depends on who is asking it and what the machine is used for. There is no single correct answer that applies across all users and contexts.
