I'm using Avast ver 170221-1 and Firefox 51.0.1 (32bit)
When I'm in the wardrobe and going though some of my items, avast keeps popping up with a message similar to this: http://i.imgur.com/s5972vM.png
It seems to be the actual wearable images that are registering as malware for some reason, not the image icon. Not sure if this is the right way to alert to this problem though.
