Eric Geier looked up for the most popular free antivirus software available on the internet and after comparing them on various aspect judged Avast Antivirus 6, the best antivirus you can get for free. The other antivirus providers tested by eSecurity Planet include AVG, Microsoft and Comodo.
Avast won the top spot because in addition to offering the regular features like protection from spyware, virus and rootkit, it also included features like real-time shields and auto sandboxing. Avast free antivirus also has direct drive access, and as a result it can be used to run a boot scan-a feature conspicuously lacking in many other free antivirus software. You can also use its site blocking and password protection features to stop other from opening certain sites on your computer.
