Your Mac is not immune to threats — yet.
Our free Mac antivirus protects on 3 fronts.
Malware can’t hide from us
Your macOS might stop some malware variants, but it can’t help you if you’re already infected. Our antivirus for Mac not only blocks viruses, spyware, Trojans, and other malware in real-time, it also scans your entire Mac for already-hidden threats.

Full Mac Scan
Removable Drive Scan
Real-Time Security Updates
Browse and email all day. You’re protected
Even trusted websites can get hacked, and criminals can easily spoof emails from your friends or bank. Avast Security alerts you to unsafe websites, blocks unsafe downloads, stops dangerous email attachments, and prevents intrusive web tracking.
Expose the weakest link in your Wi-Fi network
An unsecured Wi-Fi network is an open door to threats. Avast Security scans your entire network and all connected devices for vulnerabilities to help you stop hackers from stealing your personal data.
