I'm not totally ignorant when it comes to rootkits, spyware etc and I don't (yet) say I have one. Two scans (Panda, Comodo) didn't reveal viruses (going to try online F-Secure and McAfee as well), but I know that even rootkit revealers usually won't reveal that: rootkits (F-Secure blacklight didn't find any). This nightmare started out while researching why Apache didn't start anymore: http:Q_24412193.html
Now, my current question where I'm a bit stuck on, is this: I tried to install Spyware Doctor and it gave me an error "Access Denied" while trying to create the quarantine folder (c:\users\Abel\AppData\Roa
ming\PC Tools\Spyware Doctor\Quarantine). So I went to that folder, and it wasn't created. I created it. Ran the installer again (as admin) and same error.
Now it gets funny: I went again to that directory, this time to delete it, and now I got Access Denied myself. I checked permissions: no ownership (!!???) and tried to regain ownership (tried several admin users) and failed with all, saying "access denied". I then tried it from the command prompt to be sure I wasn't crazy and still: access denied.
Know that I usually don't have problem taking over ownership of a file or a directory. In fact, I use the "remove ownership" trick sometimes to make sure occasional users don't accidentally remove secure files (it is just to prevent stupidity).
I'm on Windows Vista Business, and the following two commands should show you my problem clearly:
g\PC Tools\Spyware Doctor" /b
C:\>takeown -f "Users\Abel\AppData\Roamin
g\PC Tools\Spyware Doctor\quarantine"
ERROR: Access is denied.
Any help on how to search for what's going on here is appreciated. I will restart into safe mode to find out whether that will help. In the screenshot the advanced security settings
