You need to all of this:
Xigncode3 fix for Injecting into AVA.
Then do this to check to see if it's gone, if not, delete the file.
Go to "RUN" and type in "regedit" and then OPEN: "HKEY_LOCAL_Machine > SYSTEM > ControlSet001 > SERVICES > xHunter1" then "Right Click" & DELETE "xhunter1" folder
Then download Ccleaner: http://www.piriform.com/ccleaner/download
Use Ccleaner and clean your PC, and then clean your Registry, and FINALLY reboot your PC.
