I have a Dell Inspiron, Windows 7 Home Premium. I had used it last night and it was fine. This morning was a different story. Unorthidox start up, McAfee AntiVirus Plus won't run, Ccleaner finally started and found way too many things wrong, keep getting pop-ups on everything. Numerous little glitches everywhere.
Have run Malwarebytes, Windows Defender to no avail. Also run Emsisoft Emergency Kit and none found anything. Suggestions anyone??
