SEP Detected risks while you were logged out.

Hi, I have SEP 12.1 instaleld and every so often i get a pop up message saying SEP Detected risks while you were logged out. You may need to open the Antivirus and Antispyware protection risk log to view and take action on the risk. When i dod this I don't see anything. does anyone have a solution on why this is hapepnnig? Do i need to re-install SEP 12.1 again? Thanks!!
