Hi I've been downloading music and videos on Limewire when my Avira Antivirus went crazy and asked at least 10 times if i wanted to deny access or delete an unwanted program so i denied and deleted them. next thing i know my background is changed to a huge popup ad and my homepage on firefox and internet explorer keep changing. I can't change the background b/c its been locked out or something. So i've been running spybot, ad-aware, spyware doctor,and superanti spyware and so far it still hasnt fixed my problem. i also did a disk cleanup. so far it only fixed my homepage problem. HELP!!!!

Maybe you could start by posting a hijackthis log? See the stickies at top of forum.
