Lately, I've been receiving the prompt, "Do you want to trust the website '[URL of website]' to use the 'Adobe Flash Player' plug-in" prompt from Safari for sites that don't appear to require it (e.g., MacRumors, PayPal). Whether I click "trust" or "not now" seems to make no difference in the functionality of the site. Can anyone explain what's going on, here? Is this a bug in Safari or Flash? Or is my computer likely infected with some sort of malware or virus? (I ran Malwarebytes; it didn't find anything. I'm running Norton Antivirus now; unless I post otherwise, you can assume it didn't find anything, either.) Or do sites like MacRumors and PayPal have legitimate uses for Adobe Flash Player? Note that I am using the latest versions of Safari (10.0), macOS (10.12), and Adobe Flash Player (18.104.22.168, as verified and updated in the System Preferences Flash Player pane). See below for screenshots. Unfortunately, I don't recall what other sites have been giving me this prompt, offhand, but they include sites as reputable as MacRumors and PayPal. I am aware that Adobe Flash Player is buggy and, in many cases, insecure. I am considering uninstalling it. For now, though, I'm mainly trying to figure out why I'm receiving these prompts, and whether I should be concerned.
