I met this before, it must be done by unknown trojan, it always creates harmful registry item key.

If you cant find the matrix of trojan, you cant win against this.



So I will give you my advices as follow, if you wanna win against this, not reinstall OS.



1. Update your antivirus program or use special antitrojan tool.

2. Try a registry guarder to scan errors and restore it.

3. Try another spywarecease tool like this.

It isnt a good choice to edit registry manually unless you know your want exactly.
