AVG AntiVirus has been available on Windows for quite some time now but it's now available on Mac.

AVG AntiVirus for Mac is a free comprehensive virus solution for Mac that protects and scans your files in realtime. Installation of AVG AntiVirus is simple and it performs an initial scan of your Mac instantly. An icon in your Menu Bar indicates when AVG AntiVirus is protecting your system. However, there are still very few security threats on Mac and AVG is best used as a precaution.

The big advantage of AVG AntiVirus Security Free over other antiviruses for Android is that it integrates with AVG Protection, a suite to stop threats to all of your devices. Through the AVG Zen panel you can control your Android devices remotely from a PC.
