I have an HP 18, windows 8.1, Malwarebytes premium, Avast premium. All programs are up to date. For about a month my computer has been doing unusual things. At one point Malwarebytes was turned off and after consulting with members of this forum I removed and reinstalled it. I've also turned on my computer and, before the desktop appeared, encountered a live, full screen view of myself sitting in front of the computer. Last night my keyboard wouldn't enter text when I typed. I signed out and when I tried to sign in again (this is a non-administrative account) I couldn't. It said I was locked out. I signed in to Admin and ran a full scan on Malwarebytes. It showed no threats. I also ran a full scan with Avast and got no threats. I signed out of Admin and shut the computer down. This morning when I booted up the computer it showed my user account as being signed in. I didn't enter the user account I signed into admin and ran Malwarebytes and Avast again. No threats. Any ideas? Is there any other type of security software I should be running? One more thing I reset the computer to an earlier time after I reinstalled Malwarebytes.
