I recently used Evans cycles website (I think they have problems with malware, looking at their f/b page) and that was the first time I noticed 'Pricefinder/coupons' pop ups dropping onto the screen. I've searched t'interweb and found guides on removing it, but when I go into add-ons manager in extensions, all I can see is an Avast update; no new add-ons or programs installed other than that. Can anyone suggest where it may be hiding, or is it something which has come as part of the latest Avast update, please?
