random cpv.srv-ad.com blank pop-up screens
Running Windows 7 and am using Firefox v-14.0.
Recently I've noticed a blank screen will randomly be poped up and "cpv.srv-ad.com" will be opened when I clicked the firefox window. I tried to have a full scan with Norton 360, but it cannot detect any problem. Then I searched a lots of website, haven't found any useful information to get rid of this virus. Anyone can help me?
