Refreshing (but not)

CAVS was recommended to me and I downloaded and instaled it (totally sick and tired of no support from Bitdefender and the poor system performance when running Norton). All seemed well until two days ago when the CAVS status changed to “refreshing” and if I try to access any radio button I get error codes (e.g. MSOC440, MSOA091, STSU440, etc.) And now my dear wife cannot receive her emails and her user profile is exactly the same as mine (mine works). She is giving me so much earache I am considering ditching CAVS and going back to McAfee. I would really like to get CAVS working.
