delf.ATB has attached itself to my startup ..DLL. just rand AVG and it picked it up. Not sure how do get rid of it. I have Nortons... Just ran a full system scan and it didnt pick it up. My husband also got something that kept making popups on his computer then it made all the files he had downloaded in zip form. Its a shame that people have nothing better to do than to attach viruses for ***** and giggles.
