I think the full path name would be ...ApplicationData\Spybot...
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.
