Trojan Horse

[Felpay]

A few months ago I got a message from Norton Anti-Virus saying that it detected a trojan horse virus in my computer. Unfortunately it could neither repair or quarantine the file. I immediately deleted the specified file (not really expecting that to solve anything). Ever since then my Dell Inspiron 8200 laptop has intermittently choked on any software graphical applications (games and simple desktop window manipulations), suffering a severe drop in frame rate. Since the virus I have formatted my hard drive several times, starting from absolute scratch, but the problem persisted. I am at a complete loss as to what else to do and would rather like to get this reasonably expensive laptop performing normally again.

Thanks in advance

I think its your network???

If you cleared your machine, started from scratch... the virus is coming TO your machine from somewhere else.

OR, the virus is in your bios.
Try a "low level" format
or you need something to check your bios?

my .02 cents
good luck

Do you know what Kind of Trojan Horse it was? There are scanner tools out there that will search your BIOS as well as your HD.

you can never go wrong with an online virus scanner too.

like larry said, the trojan could be sitting on your network somewhere. when you formatted and installed the os over, pay attention to exactly what it is your installing for apps. (especially if you downloaded it from a p2p network) it is very easy to bind files togeather. for example- binding a trojan to the norton antivirus 2k4 install package.
