Hello Steve. 
Thank you for contacting AVG Community.
This isn't the experience we want you to have. We'd like to look into this & help you.
From your description, it possibly seems to be a false positive.
Initially, we'd suggest you to ensure that the AVG program has the latest patches applied to it.
Open AVG program - click on refresh icon beside virus definitions, at bottom left corner - Restart computer after successful update & check.
If you still receive the notification, please help us with full screenshot of the threat secure popup.
Here is the link which has the steps to take a screenshot :

Thank you in advance!
