Most likely that is not a Trojan, but an adware/spyware program.

So first of all I would run an anti-adware program like Lavasoft
AdAware, www.lavasoftusa.com (don't forget to download the latest
Definition File -- or allow AdAware to download it itself, after its
installation).

I am not a computer technical person, but I am trying to get rid of a Trojan
virus thing which has appeared on my PC, which is an HP Pavilion, new in
2000, 650MHz Athlon processor, using Windows 98SE and IE6.

It is called "StartPage-DU.dll" and keeps causing my antivirus software
(Regularly autoupdated McAfee) to report that it has removed a file called
SP.dll from my Windows Temp folder. It seems to be triggered by running
Internet Explorer.

I have looked in the McAfee and Sophos web sites for advice and although
they tell me what it does, I can see no advice that I can understand to help
me locate the file in my PC which is actually causing the problem.

They talk about changes which the thing makes to the Registry, but that
seems so complex that I dare not touch it (I looked in something called
Regedit and it was full of very technical looking gobblydegook, though I did
eventually manage to find the bits it was talking about).

There was something said about uninstalling a search assist program, but
when I try to do that it says it cannot.

I tried using something called AdAware which someone suggested and it never
found it, nor did one called Spybot S&D, and I did a virus scan of my whole
machine with McAfee and it didn't find it either, but it is still there
because McAfee still keeps deleting this file from TEMP and the home page
still keeps changing.

I keep seeing references to a file called SP.html, but I can't find one of
those anywhere on my PC.

The main thing this seems to be doing is to muck about with my Internet
Explorer home page, but I am worried that if I cannot get rid of it I might
send it to other people with my E-Mails.

Can anyone give me some advice please - advice in very simple terms that I
might be able to understand please.
