Your Mac is not immune to threats — but 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. Avast’s free 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.
Real-Time Protection
Runs silently in the background to block threats as they appear.
Complete Malware Detection
Stops both Mac and Windows threats to prevent you from sharing infected files with your friends who use PCs.
Full Mac Scan
Run an in-depth scan of your entire Mac to root out hidden malware.
Removable Drive Scan
Scan any external drives (CD, DVD, USB, etc.) attached to your Mac.
Custom Scan
Select specific files or folders for faster, targeted scans.
Scheduled Scan
Schedule scans for when you’re sleeping or away from your Mac.
Security Reports
Stay informed with personalized security reports every 30 days.
Real-Time Security Updates
Receive security updates and new features automatically.
Browse and email in peace. You’re protected
Even trusted websites can get hacked, and criminals can easily spoof emails from your friends or bank. Avast Security for Mac alerts you to unsafe websites, blocks unsafe downloads, stops dangerous email attachments, and prevents intrusive web tracking.
Web Shield
Blocks dangerous downloads, and prevents malicious websites from injecting malware onto your Mac.
Email Shield
Prevents you from sending and receiving malicious email attachments on your Mac.
Online Security
Warns you of unsafe websites, blocks intrusive ad tracking, and safely redirects you to correct sites if you mistype an address. (Available as an optional browser extension)
Find and fix Wi-Fi network vulnerabilities
An unsecured Wi-Fi network is an open door to threats. Avast Security for Mac scans your entire network and all connected devices for vulnerabilities to help you stop hackers from stealing your personal data.
