My windows defender won't turn on no matter how many times I open it and
click 'on'. Every time it closes it has to be turned on again. This is
confusing the hell out of me. What's going on?

Er... I have windows vista home premium and have that KB whatever update
installed.

Hi BarkingPup,

1. Error message when you run Windows Defender: "Error Code 0x800106ba"
