The best antivirus software out there is called Active Virus Shield. It is a repackaged version of Kaspersky Antivirus which is one of the best antivirus software that you can buy. It is tons better than Norton or McAffee because it takes up less RAM and does a better overall job at protecting you. The thing that I like the most is that it is free!

NOD32 is known for not taking up much memory and having the best proactive scanning/detection. I have recommended people buy it in the past, until I found out about active virus shield. I hate that Norton and McAfee take up so much RAM, NOD32 solved that for me.

If your currently using AVAST or AVG the free version I highly recommend you use Active Virus Shield instead. It is a lot easier to use than AVG and does a much better job than either of those.

In my research for links that compared different antivirus I came across a 2nd, very highly rated free antivirus. I haven’t tested it but it is worth mentioning. It is made by a German company of the same name, AVIRA.
