Have it analysed and if found to be a false positive, the signature can be updated so it isn’t detected. This then helps all avast users that might have this installed.
I don’t believe this is directly connected to this detection.
Without more detailed info on the Explorer pop-up we can’t really say (screenshot of the pop-up window). If you aren’t using a pop-up/ad blocker in IE you should consider it.
