And avoid reformatting the drive, it will help nothing, since most probably all your USB storage devices are infected, you will need a through clean up first to be sure.....
I can give you a few basic steps if you want to try them out.
1. Restart PC in safe-mode using the F8 key.
2. Login to you windows as Admin.
3. In safe mode check to see if the processes for those 2 programs are still on.
4.If yes, kill the processes if not search for those two files in the entire HDD, all partitions...
5. When found, Shift - Del all those files.
6. Run msconfig in the start menu.
7. In the system Configurator, go to the Startup Tab, remove the ticks from the x number of processes that lead to those particular programs....
8. Apply
9. Ok... restart rig in normal windows mode and check to see if they have popped up again.
Also forgot to say after you have deleted the programs you found through your search, clear the Temp directory of everything, make sure the recycle bin is empty too.
