I was on a site to get an update on that football player who got hurt. I got all sorts of weird boxes as my anti virus software caught it. I think it stopped it in time but one box said there was a virus looking for credit card numbers. My scans since then havent found anything but how can I ensure that my computer is clean or does not have a key logger installed. I dont save cc numbers anwhere on my pc but am now worried about entering them, ever. any advice?
