The last update of AVG (Virus Database: 404 - Release date: 17/03/2004) works on Trojan horse downloader.Small.GS.
BEFORE YOU MUST STOP THE PROCESS "TASKMAN.EXE" in Task Manager Windows (you can open this with Ctrl+Alt+Canc buttons).
I have had horrendous problems with downloader.small.4.
AVG free edition identifies the virus and a scan says the infected files are healed, but they're not - the system simply crashes repeatedly. I have binned AVG completely and have had no further problems. I'm sure it's still on the system but I think I'll install McAfee or Norton to do the job with an update.
I tried stopping TASKMAN.EXE but AVG still couldn't remove the infected file so I had a look in Windows task manager "Ctrl+Alt+Del" for this too found it and stopped it as well then run AVG again. This time AVG was able to move the infected files to the vault.
How do I get rid of this Virus?

The spyware program 'PestPatrol' will remove it.
Go here for a free virus scan and removal. Be patient, this is a very in depth scan and takes awhile. http://www.pandasoftware.com/activescan/com/default.asp?
AVG for windows seems to get rid of the downloader, but sometimes it comes back. i personally don't thonk you can get rid of them uless you are willing to do a full system restore. good luck!
Have you checked at the AVG website? They have some separate programs you can download for these trojeans their regular anti virus program wont get rid of.

There are many sites that can guide you on this. One of my recommendations; http://wiki.castlecops.com/Malware_Removal_and_Prevention:_Introduction
Get Hijackthis, a freeware program. Scan for the refence to the file that AVG can't remove. Redo AVG virus scan. Reboot, repeat if necessary.
IVE just updated my avg antivirus software and run it. It found downloader.briss and removed it to the virus vault.
