When I first checked Windows Defender's History, it had one recent entries (among some I knew to be false positives) labled:
Service: UYMTE
File: C:\Documents and Settings\Administrator\Local Settings\Temp\UYMTE.exe
I checked the directory and nothing of that name or similar was there. So, having noticed all the clutter in my temp directory I fired up ATF-Cleaner and cleaned out the temp directories and reclaimed a few GB of HDD space. I then used the program "Eraser" (a file shredding program) to overwrite any files left in the temp directory noted above, with the exception of the temp files for a game (NWN2). After I was done shredding a few dll files reappeared so they got shredded too. They didn't reappear again. I had hoped that was the end of it. Then a while later I checked the history of Windows Defender again. It had two new entries as follows:
Process: pid:1736
Service: RFGIKZN
File: C:\Documents and Settings\Administrator\Local Settings\Temp\RFGIKZN.exe
And
Process: pid:3600
Service: EJRJBCDJ
File: C:\Documents and Settings\Administrator\Local Settings\Temp\EJRJBCDJ.exe
Of course upon checking, none of those files existed. So I ran another scan with AVG Free, and with Ad-Aware SE Personal. AVG came up with nothing and the only thing Ad-Aware found was a tracking cookie in IE (which I never use but someone else does to check their email despite my persistent protest.) So with no other real options left I downloaded HijackThis once again and ran a scan. Here are the results:

I would like to note that I have observed neither malicious activity nor direct evidence of an infection other than the randomly named suspect files. However I'd like to assuage paranoia and ensure that my computer be clean. Any help will be greatly appreciated.
