Either virus or spyware?

[Geoff]

Right now, my standard av hasn't found anything, while trendmicro found 5 infected files. I could delete 4 of them, but not the fifth, because it was currently in use:
TROJ AGENT.ABS c:\windows\system32\vzemuq.exe

Panda is still running, and has scanned a lot more than trendmicro (and thus, more than crappy Symantec). 500000+ scanned, 22 infected files, 1 disinfected.

Edit: Update, Panda done, 1 virus (disinfected), 23 spyware. :/

Try running your computer in safe mode, then run your antivirus program and an antispyware program.
