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.
