How can I remove these two trojans?

I have two trojans. Downloader.Small.5N in my documents and Settings\user\local settings\temp\Dload.exe
And Downloader.Axload.C is found in windows\system32\comload.dll
I can't find any info about them anywhere. I've tried all the top
Antivirus companies but to no avail.
I've found I can't use system restore in XP pro. What are they?
And how can I get rid of them? I found them with AVG, and put them in the virus vault. However I still get pop ups saying I still have them, even after deleting them from the vault.
Any help?

Download "Mcafee avert stinger" (search for it on google) it should remove it for you! along with loads of known trojans and viruses.

Thanks P@PP@N P
But I did what Simon said in answer to the question:
How do I get rid of this trojan?

This action also got rid of my two trojans!
Thanks to both of you!!

As far as I'm concerned (and I do this 4 a living:) the only sure way of getting rid of thoose trojans is to install NAV200x and disable "system restore" and restart in safe mode and do a complete system scan! That would do it!
