Tody my comp was hit by a new virus called "byXpFuUK.dll".I couldn't find anything on it on the net! So I am posting MY solution on as many forums as I can.The only way I was able to delete it from my C:Windows/System32/byXpFuUK.dll was by downloading the "unlocker" program and forceably removing the "driver" from System32.Doin so causes your system to reboot due to an error however,the system then reboots and after immediatelly empying my recycle bin VOILA! All systems go! Hope this is helpful as I haven't seen any posts on this issue anywhere.
