Just finished a new build (http://) and I am wondering what is a good anti-virus software. I heard good things about Trend Micro, BitDefender, and some others; but I am not certain which one to choose. I am here hoping that the people of Tom's Hardware will guide me in the right direction. So I guess I am asking, what are good anti-virus softwares? Also when saying if they are good, or not, please specify a reason so I can understand why. Thanks in advance!
