Windows Defender

I have windows defender and when I shut down my pc each time I restart I
must manually start up the windows defender. I want it to auto start
when I turnad on my pc how can I do this. I tried the option in the
windows defender program and it doesnt work, so I think it maybe my AVG
or adaware. I am not sure and have no idea how to find out or fix it.
PLease help
Hello,

If
you have used the launch at startup option, and Windows Defender isn't
launching, most probably it wants to prevent any conflicts to be caused
on the system.
