Free antivirus has a catch-22: the products are real, but the business model means every vendor holds features back to nudge you towards a paid plan. We installed the free tiers of the leading suites and tested what they actually block — and what they quietly leave out. The ranking above reflects free-tier protection first, upgrade value second.
Scores are not pay-to-play. We combine independent lab results with our own hands-on testing of detection, performance and usability. Affiliate links never change a ranking.
Every product above gives you genuine signature- and behaviour-based malware scanning at no cost — that is far better than nothing. What you usually give up is the safety net around it: ransomware rollback, phishing protection in every browser, firewall control and support.
A single device, careful browsing habits, and no online banking or work data: a top free tier plus an up-to-date operating system is a reasonable baseline.
If a device touches your money, your identity or your job, paid protection is cheap insurance — first-year deals on our main antivirus ranking often cost less than €2/month and add the layers free tiers withhold.
Yes — the products here have genuinely free tiers with real malware protection. Vendors fund them by offering paid upgrades, so expect upsell prompts and missing extras like firewall control, phishing protection and support.
Defender is a solid baseline, but independent labs consistently rank the top third-party engines higher on zero-day detection, and Defender offers no cross-browser phishing protection or identity tools.
Reduced protection layers (often no anti-phishing or ransomware shields), no support, and regular upgrade prompts. Some less reputable free products monetise your data — none of those make our list.
We recommend paid protection for any device that touches your finances: banking trojans and phishing are exactly the threats free tiers cover least well.
