I have to manually turn on my Windows Defender (W/ 7) every time after I have shut my computer down. I always completely shut down this computer when I am finished with it. Apparently from what I have read above I have another program which is doing the same function and is overriding my Windows Defender. The message is always the same relating to Your Windows Defender is not running, and then something about another program. I have scanned my computer with all of my security system and do not see any problems. Windows Defender did remove some potential threats when I turned on full scan last night. My question is where do I go within my computer to see what program is overriding my system. It has to be another firewall I am thinking.

In reply to marie. Hello Marie. Yes, you must uninstall any other antivirus from your computer before you try to enable Windows Defender.
