your help is most appricated.

THANKS IN ADVANCE.. I need this fixed bad

You might try loading the WinXP install CD and run a repair. But I wouldn't feel safe without a format and reinstall. Do you have a backup just prior to catching the virus?

Nah... Read this.... carefully...

You my need to uninstall / reinstall your antivirus and firewall.
get serious about security.. This one isn't serious. the next one may be !
All this is is a keystroke recorder.
You need
script defender@ www.analogX.com
diamond registry protector !!! Google search for it.
a GOOD firewall...Sygate or Zone Alarm and keep your antivirus updated...DAILY !
Look for a trojan hunter/ killer..
I use Trojan Remover.. free... Google search.

never mind.

I found out how to remove it through google.

but upon scanning my 2 system I found 4 trojans (NAV didn't tell me what they did) so I deleted the files

and found 2 other viruses which NAV repair...

damn teache me a lesson about d/ling off kazaa and not scanning them...
