Hello and thank you in advance to anyone who can help me. I have two issues:
(1) On-access scanning turned itself off and I am not able to turn it back on. When I clicked on the button next to "the on-access scanner is off", it just says "Start scanning" and is greyed.
(2) When I try to do an on-demand scan, it scans for less than a second and stops. Message says no threats but "issues detected".
Here is a log I came across if this helps:
