Hi TFM,
The tracking cookies should be the same as what Norton finds. Superantispyware regularly flags up cookies for me, and to be quite honest, as I understand it, they aren't really anything to worry about.
You should be fine, now that they have been quarantined...but I would certainly advise you to do the whole process again. If you find they re-appear, turn off System Restore, then go through the process again. Some people might suggest not to switch it off, but the virus might get backed up, so the only real way to make sure is to switch it off, in the event that they re-appear.
I tend to do a quick search of the virus names if I ever pick anything up, just to try and find some information about it/them. Some viruses are more common than others, and sometimes it can be difficult to get hold of any real information as to what the virus does...someone else with some real knowledge on the subject might be able to help out here.
Either way, it's good they're gone now. Just keep an eye out, and let us know what happens!
