Our Download of the Day is avast! Free Antivirus for Mac.

Rest assured with our latest technologies, now available for Mac

avast! Free Antivirus for Mac now contains the same light, award-winning, certified, and highly acclaimed antivirus and anti-spyware engine as its avast! version 7 Windows counterpart.

Shield yourself from increasing web-spawned threats

Our new Web Shield for Mac transparently scans all visited web pages (port 80), downloaded files, and java scripts, supports IPv6 connections, and - with its intelligent stream scanning feature - doesn't slow your surfing.

Improve your Mac email security

Our improved Mail Shield scans for malware in all emails sent and received. Mail Shield serves as a proxy email server, so if you access a mailbox using a secure connection (SSL) you must configure your email client and the Mail Shield to support this type of connection.

Guard your Mac from infected files

Our new File System Shield performs real-time scanning of opened/executed files, to stop infection before it spreads. If you prefer, you can set a list of files and/or directories that you would like to exclude from scanning.

Know what's coming before you click

The browser plugin for our cloud-based WebRep technology provides website reliability and reputation ratings according to community-provided feedback, as well giving you greater protection against phishing sites and fake/planted SSL certificates. Now extended to support Safari™.

Maintain full control of your scanning options

Use our on-demand scanner to perform your Mac virus scans the way you like, with the ability to select either full file system, particular folders, or even removable devices.
