So this popped up when I was reading the news on a site that was not Adobe. Anyone else seen this? It looks similar to the one going around claiming to be a Firefox update. The filename has some strange website in it. I have looked for Adobe support to report this to but I have found none.
If you get this, don't let it download into your machine. I'm not sure what it is, but I bet it isn't good!!!
Try the forum for Flash Player.
Definitely not an official Adobe site. Most likely a malicious ad or something. We do get reports of these and I forward them to our fraud team for follow-up. I'll forward your screenshot to them.
If this happens again, from this site or another, please send an email with the complete URL to email@example.com
