Virus please helpmy computer?answer please?

There is something I've done twice in the past, but I don't recommend it unless every other option has failed. Before trying my suggestion please try the following. Download any single free anti virus software and scan. if it detects nothing then uninstall it and download another, and keep doing this until one detects it, one will after a while. I have always had lots of luck with AVG 7.5, and AVG 8 is now free from www.grisoft.com. If you download an anti virus program that detects the virus but cant fix it, lock it in the virus vault (AVG has a virus vault. other programs have other names for it) then uninstall the software, the entire anti virus program, and when prompted tick the box to include everything in the virus vault. This should remove it from your computer. If it fails try this. Back up all your personal files and make a note of all computer information you need to remember. Then carry out a system restore to a highlighted date before you got the virus. This should get rid of it. if it doesn't then try the following. and this is the bit I urge you not to try unless everything else fails. If you have a windows disk you will need it. if you don't you will have to make a back up windows disk from the percentage of your hard drive set aside for this purpose. once you have your Windows back up disk, reset the hard drive to factory settings. Format the disk completely. This will be quite a long job, and you'll have to re install windows and all of your personal settings and files, but you will end up with a computer that will be just as it was the day it was made. Completely clean. It's drastic, and a last result, but I've done it twice and it works perfectly. PLEASE ONLY DO IT IF EVERYTHING ELSE FAILS. Once you are up and running again download decent anti virus and anti spyware software. I have used the following free combination for ages and have never had any trouble. 1.) Windows default firewall. 2.) AVG 7.5 (Now 8) 3.) Spybot Search and Destroy. 4.) Spyware Blaster. Good luck.
