So as of late ive been getting these pop ups. in most cases I would think "alright run some adware/malware scans and check for updates to the pop up blocker. However this one has me stumped. The pop ups are coming through the steam browser. Which I don't know how to fix. I ran malwarebytes, super antispyware, comodo, and spybot, alas no luck. tried reinstalling steam as a last ditch effort but again no luck. I attached a picture of the pop up, roughly 90% are about a video player update, ranging from a generic "your video player is out of date" like the photo to ones who mimic flash. There are others but malware bytes blocks the page from loading some of them.
