I think the full path name would be …ApplicationData[i]Spybot…[/i]

Spybot backs up any entries it deletes in zip files there in case you find out you shouldn’t have deleted them. It zips them with a password so that other scanners like AdAware etc don’t constantly spot them and register that you still have these spy/malwares on your system. Avast (and any other scanners) can’t access these files because of the password.

The administrator@advertising entry, for example, was probably a tracking cookie that you told Spybot to delete at some time. If it wasn’t zipped and locked with a password then every time you scanned with spybot or adaware… they’d detect it all over again.

There’s no need to fear any infection from these - they’re locked away quite safely.
