I used to run all the free antivirus programs, and still got virusses, until the Computer Fundies said to me that running more than 01 antivirus at a time, is not recommended as they work "against each other". Anyway, I bought Kaspersky internet security and it is definately way better than anything else I have ever put on the Pc, as well as the fact that it has an amazing free internet security for your cellphone, you choose your cellphone from a dropdown list, and download. Btw, I heard he was the guy that wrote antivirus programs for the Microsoft Empire's Computers or something like that...
