PC_AntiSpyware2010 and Advanced Antivirus. It is also known by the anti-malware companies by one of its common filenames, Braviax.exe.
Fixed one of these this week. A bitch.
The customer is on contract, so it wasn't a time and materials thing, fortunately for them.
Bitdefender live CD ran, found stuff. The scanner crashed (*poof* and it's gone) shortly after being told to deal with what it found. Too bad. If it'd worked, it would have been a nice thing to give to the end users, for them to run first before they call me in.
Couldn't get anywhere near cleaning it with tools running on the system itself. Stuff just kept coming back.
Pulled the drive, scanned it with 1)Symantec Endpoint Security, 2)Malwarebytes and 3)Superantispyware. Each successive program found more stuff.
Reinstalled the drive. Scanned with locally installed Malwarebytes and Superantispyware. Had to run a TCP/IP fix to get malwarebytes to update itself. Each found yet more stuff. Cleared some security blocks that the nasty had left in place (to keep you from running task manager and regedit). And....Couldn't run Windows updates. Couldn't start the Event Log service -- some missing critical piece.
"Aw, ***t!"
Repair install of Windows, plus all updates.
Then, something along the way had put a limit on the user profile size (computer is not on a domain, BTW). A bit of Googling found the fix.
Way, way too much trouble. Next time it gets backed up and blowed away.
