Hello neeko and welcome to Seven Forums.

I think I'd give System Restore a try if you have a restore point that goes back to a date/time prior to when the problem began. You may have to try in Safe Mode.

If you can do a System Restore I'd then run a full scan with the free Malwarebytes. You can download from the CNET site using the big grray button on the left that says Download Now (9MB).
