Most of the time we have observed that many anti virus just clean the malwares they dont restore registry settings changed by Malwares. I read some where KasperSky also restore registry settings infected my a virus, but i m not sure.
So to solve this problem you should backup your registry, but before backup registry keep one thing in mind that your computer should be virus free.
Procedure:-
- Ist go to Run and type regedit and hit enter, you will see registry editor( if nothing happens or pc shows some error then your PC is infected, clean it)
- Go to File and then Click Export. See image
- Then select the path to save the file and save it with the name WinRegBak.reg
- Now it's done.
To restore Registry:-
- Double click the .Reg file that you have saved.
- Computer will ask Do you want to merge setting" click Yes
- Most of the settings will be restored by this.
