Add Exclusion for PUP

[Hardcopy1]

I know that I can add an exclusion for various detections by using the ADD EXCLUSION tab in Settings.  My situation is that Anti-Malware 3.0.6 is detecting a PUP which is only a Windows Registry Key.  None of the exclusion options seem to fit this circumstance. I've looked at the item which was identified and I want to add an exclusion so that I'm not told about it every time I run Anti-Malware.  The identified item is for Dell System Detect.  Can someone tell me how to exclude this item (see Quote below).

To exclude that item its really not straight forward.. you can see this post HERE on how to do it...

On the other hand this could be a false positive and you can report it HERE just in case...
