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

Malware isn’t the only threat to your Mac. Malicious websites and vulnerable Wi-Fi networks can also jeopardize your safety. Avast Security provides essential free protection against all 3 threats, and our new Pro version goes the extra mile to expose Wi-Fi intruders and stop ransomware.

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.
