Ok, I have a windows 10 PC problem. Its either malware or a virus or whatever else there is. Antivirus didn't catch it. It wont let you open your start menu or search with cortana. After a while even the mouse stops working. I tried to press shift then restart from the login to do a system restore, reset, everything. It blue screens after about 5 seconds saying WDF_VIOLATION. Do any of you have a idea. Also I lost the windows repair disc.
