which antivirus is the best

I would say Comodo Antivirus, it comes with Firewall included wich are the two things you need to be safe in the Internet. I thought it was Avast! but turns out Comodo Antivirus was the only one that found some virus in my computer when I used windows. I unistall it and installed Avast! as everyone was talking about, it never caught another, I gave it time so I unistall Avast and put Comodo again, there it was, there were viruses and I didn't know about it. But Comodo found. You can find Comdo Antivirus here: http://antivirus.comodo.com/
