Hi recently having the same issue dated 13-11-2018. In full scan of my computer found a treat HEUR:Trojan.Win32.Generic in C:\ProgramData\mssnjvao.exe when trying to resolve it asked me to delete and reboot. I tried that option and it kept on doing advanced disinfection all night but the bug was not removed. I could not manually reboot as shut down option is not available now. I couldnot open browser too.. help me plz..
