Trojan dropper; a returning problem - help?!

So I've been reading up a lot on these nasty Trojan Dropper and I'm afraid I've come to the conclusion that I need help. After discussing it with a friend, I browsed the net, and this forum as well, for solutions.

In the first row, I actually suceeded in removing what seems to be the core problem, the wvusq.exe file with ComboFix, but after a reboot, I realized that the file ddaxv.dll was still corrupting my computer. I got a hold of the program, Vundofix, but it didn't show up on any scans and after yet another reboot, the machine was just as infected with the original wvusq.exe and whatever, that ComboFix now cannot remove !

I've been through the Read & Run thread and have thus attached two logs. The Spybot found nothing, and the AGV Spyware only caught a cookie and then a dgu Trojan, but nothing was reported even though I specifically (and very carefully) followed the instructions to let it log everything even if it wasn't a threat. I can't find any reason as to why it didn't log it. So sorry.

I really hope you can help. It's also killed my AGV Antivirus.

Any help would be much appreciated. Thanks in advance.
