This is how I got rid of Antivirus XP 2008. It is different than the XP Antivirus 2008 most sites refer to.
First you need to stop the program from loading on startup. This is what you do to stop it:Run msconfig, Go to Startup tab
Click apply, then ok, Restart computer
Then you need to delete the main files this program uses. Delete the following files:
This should remove the program from your system but you probably still have a warning message displayed as your wallpaper in Windows and the virus removed the ability to change the wallpaper or your desktop settings.
To restore ability to change your desktop settings and select a different wallpaper and screen saver do the following:
Navigate to User configuration, Administrative Templates, Control Panel, Display
Right click on Remove Display in Control Panel
Click on Properties and select Disabled
Do the same steps to change the following attributes to disabled:
Hide Desktop Tab
Prevent changing wallpaper
Hide Apperance and Themes tab
Hide Settings tab
Hide Screen Saver tab
You should now be able to use your computer normally and change the wallpaper to something other than the warning message Antivirus XP 2008 set it to.
