Best Free Antivirus

I always have come across a frequent question as to which Anti virus is the best to protect the Computer, and obviously free of cost. 

Personally, I have always had faith in Mcafee 8.5i, and still using it. The only overhead using this anti virus is of downloading the update file and then updating it, where the update file is of size more than 100MB. But considering the fact that its a cost free anti virus, and the performance of this anti virus, the overhead is worth. 

However, there are other free anti viruses also which are among the favorites, around the world. One of the best website reviewing about one of the best anti virus in the market today, has their favorites as Avira and Avast. For more information, click on the below links :-
