i had the virus a couple days ago and to get it out of the system i ran AVG virus scan. you can download a free version from www.avg.com once you run it, make note of the file the virus is in. avg will not clean or quarantine it. though once it finds it you can delete the file by restarting the computer and locating the file. you may have to run avg a second time after you reboot but it will eventually allow you to get rid of the file off your hard drive. feel free to email me if you need some help with it.

The spyware program 'PestPatrol' will remove it.
try free antivirus software AVG
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!
virus virus
There are many sites that can guide you on this. One of my recommendations; http://wiki.castlecops.com/Malware_Removal_and_Prevention:_Introduction
IVE just updated my avg antivirus software and run it. It found downloader.briss and removed it to the virus vault.
Trojan downloader is I think spyware so get spyware doctor or a strong antivirus.
I shifted mine by pressing F5/F8 lots during bootup, going into safe mode with command prompt, and deleting them there. Ask an adult to help you ;)
