Your Mac is not immune to threats.
Our free Mac antivirus protects you on 3 fronts

Malware isn’t the only threat to your Mac. Malicious websites and vulnerable Wi-Fi networks can also jeopardize your safety and privacy. Avast Security for Mac provides protection against all 3 threats, and our new premium version also exposes Wi-Fi intruders and stops ransomware.

Anti-malware protection for your Mac

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.

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.
