Which virus killers are best recommended? I had Mcafee installed on my PC before windows went wrong. I now can't get it to install and update (but the firewall part works OK). I found a 3month trial of Panda Antivirus on a coverdisk which I have installed. Looking at Panda website one copy of the Virus killer and Firewall will license 3 machines for a year so I am tempted, whats the verdict?
