Anti Antivirus = ? Virus ?? Trojan ??

Tried Scanning in DOS with various AV soft - No virus found.
Also scanned from windows (other partition OS) - No virus found.
Either the virus/trojan was hit and run - self destructive and only script error is remaining or not with in the scope of AV softwares.
Hoping the first case to be true and having no virus etc in my computer how can i correct this Internet explorer Script error
Access Denied.
If i can overcome this ?
If i can do this then I think most of the problems are solved -- Hope so.
(I have already Reinstalled IE from WIN XP CDROM.)

I will try dl Kapersky AV once I have better connection speed ( atleast 3 kbps dl speed !!)
