Avast! Free Antivirus:One big reason I included avast! Free Antivirus as a best free antivirus program is because of its “heuristics engine” which can detect previously unknown viruses and other malware. During the avast! installation, you’re asked to install the free Google Chrome browser. It’s not required so if you’re not interested just uncheck the box. Download it
AVG Anti-Virus Free 2012:The huge number of premium features, frequency of updating, and install-it-and-forget-it aspect of AVG’s Anti-Virus Free really do make it the best of the best free antivirus programs available today.Download it
Microsoft Security Essentials:Two of the biggest reasons I added Microsoft Security Essentials to this list of the best free antivirus software is because it’s directly from Microsoft and also because it’s very easy to see if you’re computer is secure from threats: if the icon next to your clock is green, you’re in good; if it’s red, something is wrong.
Avira AntiVir Personal:The scope of malware that Avira AntiVir Personal can keep you safe from is alone enough to make it one of the best free antivirus software programs but the heuristics and ease of use add to its value too.

Pc Tools Antivirus Free: Low memory usage but high CPU usage – strange!If you are someone who schedules scans rather than using them on demand then this may be a good choice but I myself will steer well clear of this one.Download it
IObit Malware Fighter:A bit of a mixed bag this one – spotted problems other programs missed but I’m not entirely convinced that virus definitions are updating properly.If they are then this is well worth consideration. If they aren’t then you will likely want to skip this one.
