While typing documents Microsoft Office somebody keeps typing a single letter to destroy what I have typed. Example: MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
Even when I just did that it seemed to get stuck and wouldn't stop until I kept hitting the space bar.
One day I noticed on startup that I got a message that read: Intel - "Active Management Technology Enabled. To enable or disable Intl AMT, contact your authorized system Administrator. Intel SA 00075 Detection Management Tool."
A few days later my computer said: "Desktop Restored" -- and it looked slightly different so I logged off and back on again and it returned normal. It had also said: "You have logged on as another computer..."
Another day a message asked me to complete my group networking by creating a password for my group, but I never requested a networking group.
I did eliminate group networking, and refused to make a password. I also downloaded Crypto Prevent, Key Scrambler, and Bitdefender instead of Avast. I also have free versions of Super Anti-spyware, and Malwarebytes. I locked my desktop and have encrypted some of my files with passwords. Since downloading Bitdefender I haven't noticed any interruptions with single letter shown above in my example, but when it was happening, it also happened when commenting on Yahoo news and showed up everywhere I would normally type. I had to shut down my computer and restart to stop it. Any suggestions as to what this might be?
