Help with Malware – msgrap.exe

Hello,
Since two days, my system has been infected with malware, Ainton.AA worm, I used Malwarebytes free version, it didn’t remove it all, my NOD32 identified the worms, but wasn’t able to remove them as they were running in the process.
1. ntdlr.exe – which later I manually deleted in safe mode. NOTE: It was taking 50% of the CPU usage and after deleting it, the usage was freed.
2. msgrap.exe – this still runs in processes and gains 50% of the CPU usage, I upgraded my NOD32 4 Security Essential to NOD32 5 Security Essential, but it failed to detected any virus or worm.
and this msgrap.exe still is in my processes under my user and not under SYSTEM, I have to manually end process tree for my system to work efficiently.
Any suggestions on how to identify this worm/trojan and how to get rid of it??
Google fails to provide any information on msgrap.exe!
I’ll be looking forward to something pertinent.
