McAfee Real Time Scanning not working on my Mac

Installed free McAfee Multi Access Internet Security Suite through my AOL premium account. It used to work great but about a week ago I noticed a red exclamation point, indicating "Real Time Scanning is not working". When I check my settings it says It is turned on, however, when I look at my preferences it says it is ON. See screenshots below. My question is how can I fix this problem? Thank you!
