When I start up my computer, I get pop up saying Windows defender is turned
off with the red shield with the X on the bar. I try to turn it on but search
says no new definitions found. However, when I click on START button and
programs and click on Windows defender, I get green shield with checkmark in
it. Is it on or off? If off, how do I turn it on.
