trojan virus issue - combofix.exe locked up

i've contracted a trojan virus and during running of combofix.exe, it got hung up due to presence of pev.cfxxe. After several unsuccessful attempts to kill that process, i eventually had to stop combofixe.exe and then i could remove both pev.cfxxe and NirCmdC.cfxxe from the c:/combofix folder. I found the combofix log and it is attached.

then, i ran the MGtools.exe utility. it ran successfully and i've attached that log as well (mglogs.zip).

i just want to check to see if there's anything still haunting my computer, especially since combofix.exe didn't fully execute to completion.

many thanks for any help you can lend.
