Advanced details doesn't show advanced details

When exiting from an idle period a small window informed me that a quick scan was done and that security risks were resolved.  When I went to the details screen it showed that one security risk was detected and that one security risk was resolved.  It didn't say, however, what that security risk was.  I even expanded the details by clicking the plus sign but there were no further details.  I want to know what this risk was.  How do I find this out and why wasn't there any detail in the advanced details window?
