Hi,

please read the link "VirusRemoval" below in my sig.

if you can't solve the problem yourself,
e.g. by moving the file to quarantine in safeMode or via boot-time scan
then please come back with more info,
e.g. a Hijackthis-log and results of onlinescanner on the file

Here's some info on the trojan/worm:
