here's my two cents; if u want to buy an antivirus, [b]kapersky[/b] and [b]nod32[/b] are the best ones you can find. if you're looking for some free antivirus softwares in the internet i suggest these three 1. Avast 2. Avira Antivir 3. AVG these are the top three if u ask my opinion norton and mcafee requires a lot of memory, thus slowing your PC so I wouldn't suggest it
