Something called FriendsChecker has been adding links to the web pages I visit, just like oyodomo did. I have Webroot antivirus now, and it hasn't found any threats. Earlier today I ran scans with AdwCleaner, TDSSkiller and ESET, and they all reported no threats, but it sure looks like a virus to me. Is anyone here familiar with FriendsChecker? I want to remove it, but don't know how since none of the scans turned up anything. I'd appreciate any suggestions. Thanks.
