Hi blackcar28
AVG is excellent but it's worth just trying another scanner.
Have you tried any free online virus scanners ? Sometimes using another one will do the trick. If you look at the top left hand corner of this page you will see a link for 'Free Online Virus Scan'
Also try downloading and running 'Spybot: Search and Destroy' and 'Ad-Aware SE'
If that is no help to you then you need to post your Hijackthis logfile on the 'Hijackthis support' forum.
Download Hijackthis and make it a folder of its own, show us the logfile and a moderator will check the log.
