Anyway, I have a Trojan that I can't seem to get rid of:
This is the result of a Scan by Spyware Doctor Scan Results: (edited
to just show location)
C:\Program Files\BitTorrent\uninstall.exe 
C:\Program Files\CCleaner\uninst.exe  

I'm not familiar with Spyware Doctor. Does the above mean it detected
the trojan horse in those files?

C:\System Volume Information\_restore{593F298F-B7D6-4A3D-A260-6D7E68E3F587}\RP233\A0427654.exe

That looks like a restore point of Windows' System Restore feature.
Either the trojan horse managed to write itself to that location (or
infect a file already present there), or it got there when System
Restore created a restore point.

I attempted to access the C:\System Volume Information... file but it
would not allow me to access this;

As per default the "System Volume Information" folder is accessible only
by the user SYSTEM. However, as an administrator you can take ownership
of that folder and assign access permissions to yourself.

I was considering running as System permissions to manually uninstall
the restore loction, but didn't want to give the Trojan any more power
(Administrator is bad enough).

Anything running with admin privileges can assign itself any other
privilege it might need, so altough it would still have been unnecessary
to run anything as SYSTEM, it wouldn't have made any difference.

On the third time of removing and rebooting the infection is no longer
being picked up by Spyware Doctor... My question that I pose to the
online community is this: Do you think the infection is actually gone?



Lather. Rinse. Repeat.
