Help to remove this file

Hi,

My sister's computer every time when running Internet Explorer 7, I noticed a short message appear on the 1st line of IE tool bar, " Virus is now ATTACKING your system from MAnz_Shidah".
I scanned with antivirus/anti-spyware but could not fine any affected files.

The only 2 log files I found on HijackThis were:

a) HKLM\..\run:[manz_shidah_virus]wscript.exe
C:\windows\system\manz_shidah.js

b) HKCU\software\microsoft\internet explorer\main, Windows
title = Virus is Attacking your system

I also noticed there were a Jscript file = Manz_shidah and HTML document = Attach your system appeared on all harddisk partitions which were not be able to delete.

Please help, thanks

Hijackthis can remove the registry entries and if you go into the misc tools section of Hijackthis you can select files to remove at reboot.

Your antivirus can not find the affected files? That is a new virus?

Hello,
When I download programs from the internet fresh download keeps popping up and asks me to register. It won't let me download anything. I removed it in the controll panel and used an antivirus program to unistall it. It went away for a few days then it came back and I can't find it on my computer.

Pease help, thanks
