Quick decision
I don't trust big security companies with my data
You've read about telemetry, data collection, and the irony of antivirus software that monitors your behavior to fund itself. You want protection that doesn't make you the product.
F-Secure. Finnish company, documented no-data-selling policy, used by governments and enterprises across Europe. Narrower product scope means less attack surface and less telemetry by design.
F-SecureFits if the privacy of the antivirus software itself matters as much as what it detects. Finnish jurisdiction, GDPR-native, no third-party data selling documented in their privacy policy.
Go to F-Secure
ESETMakes more sense if you want stronger detection alongside European provenance — Slovak company, EU jurisdiction, no US surveillance-alliance obligations.
Go to ESETNoteEvery antivirus product collects some telemetry to function — the question is what is collected, where it goes, and who it's shared with. F-Secure and ESET have cleaner answers to this than most, but neither is zero-data.
