Fast scan gives same Tracking Objects even though they have been removed by a previous scan

[DocBri70]

Nearly every time I start up, I get an alert telling me to scan.

I do a fast scan and, invariably, I get the same number of Adware.TrackingCookies (38). I remove these but the next time I start up and do a quick scan they are back! Help!!

I use Firefox and Windows XP

Thanks GuiltySpark - I'll try this. I think I was coming to that conclusion myself!
