AVG found that as the only one, but Nortons found nothing and neither did Mircosoft Security Essentials

Download Spybot Search and Destroy or Super Anti Spyware.

They are more specific for removing Spyware and Malware and will find things missed by the others which generally will only search for viruses.

A scan with SSD or SAS will do a better job.

Either will also not conflict with AVG and should be fine with MSE,(no idea on Norton's,which I don't like anyway as it seems to miss to many things or give false alerts).
