Once you have confirmed an infection on a system, the ONLY proven way of getting it again to a trusted state is to rebuild it from scratch, that is, reinstall Windows from a known safe media. Make sure to backup your important data beforehand with the help of an external operating system.

As they say, If a bad guy can persuade you to run his program on your computer, it's not solely your computer anymore

Yeah first i try other methods if i failed the only method left for me is to reinstall the windows and backup my data

If you have a system image from a period when you were not infected, now would be a good time to do so. You can try and remove malware/viruses, but personally, I keep numerous images in the event that should something like this happen (which hasn't in many years) I would simply nuke the system and return to a time when all was well
