A Suspicious Script

[Carrym]

My PC is attacked by a Suspicious Script called "NTDETECT.exe" which is harming my PC's parformences. It's symtom is when i double click on my disk drives to open then cz of this script drives dont open. Instead my virus guard notify me about this script. It also denies me to unplug any removable drive. Can anybody tell me how I could get rid of this without formatting my HDD.
I would be grateful.

NTDETECT.exe is part of Trojan.W32.Small.

make sure you have some good AV installed. scan entire PC and remove any traces of it

certain anti-spyware programs should remove also, you can try spybot
