It's perfect for checking suspicious files before launch—no ads or subscriptions!

Installation takes just two minutes for Linux users, and for Windows, there's a full tutorial that bypasses some of its quirks. Learn how to make ClamAV user-friendly: add it to your PATH, configure freshclam, and configure the registry for one-click scanning.
