Hello everyone.
I was servicing a customer's computer (I work at a computer repair shop), and was having a helluva time trying to identify exactly what was wrong.

His Microsoft Outlook program was being used to send people spam e-mailings for an "Online Casino"
If it helps, the title message read: "try this new, Online Casino, for free!"

I ran AVG Anti-Virus - and that came back with a clean result.
I then ran SUPER Anti-Spyware, which came back with 38 Tracking cookies, and then second time was clean.
Then ran Spybot S&D which returned with two vulnerabilities, both for Windows Security Center, both were fixed, but neither resolved the e-mail hijacking.
I then proceeded to run Panda Anti-Virus / Kaspersky / SmadAV / Avast / ZoneAlarm / Ad-Aware & BitDefender. All of which came back clean.

Approximately 20 minutes after the last scan, a pop-up for www.freeantivirus-scanonline.com came up (Do not go to that link, it's just a reference)
and a whole bunch of pop-ups followed, so this system is obviously still infected.
And the systematic e-mails are still going (albeit it at a reduced rate from before)

Things I noticed:
Every 30 seconds or so the mouse cursor lags behind, and a new e-mail is usually sent out.
The C:\ root directory was jam packed with *.tmp files. All files had 3 hexadecimal digit filenames. (IE: 3fa.tmp, 60e.tmp, etc...)
Firewalls were being disabled automatically (Windows/ZoneAlarm)

So, I deleted the *.tmp files, and did a search for all files created the day the spam mailings started, and deleted a few suspicious looking files there. That's when the spam e-mails dropped from once every 30 seconds, to a small burst of 15-25 every 30 minutes or so)

Here is the HJT log:

End of file - 5081 bytes

Relatively small compared to others I've seen.
I know I've crippled whatever is on that machine, but I also know it's not gone.

Any help?
If you need any more details than what I've given (I tried to be thorough), I will provide them as requested.
However, as this was a customers computer, I do not have access to it to run scans until Tuesday (5/27/08), so I'm looking for suggestions.
