Let's check with it. Provide us the screenshot http://support.avg.com/SupportArticleView?urlname=How-to-create-a-screenshot of that detection message with full path to have  better understanding.

Click on "See details" at bottom right corner of that detection message to view its full path. May I know at what instance you are receiving this popup?
