Can't Get Rid of 'ADTRGT' etc. (not sure what else)

Hi, I've disabled 'Internet Explorer' and am using 'Firefox' but IE still pops up saying 'Can't Find Site' http/ url adtg.com (with long name after). I had some other problems and was able to find/delete them with "AT&T Spyware". This one doesn't seem to use the same name so I can't find it by searching. Also can't find the 'Run' button in 'Start' and the 'Shutdown' is "Logoff" only. Thanks for any help. Nick.
