Hello, I saw a similar thread posted from May 3, 2016; however, the file's "source" may have been different. Or, the circumstances under which the "update notification" showed up on my computer may have also been different.
In any case, I'm posting what I saw--and what actions Norton Security apparently took a few minutes ago--to try and determine if this really is "a genuine Adobe Flash update," or a "false positive." (My assumption was that it was a FAKE UPDATE and so I did not download nor otherwise try to execute the file--I simply closed the browser window.)
NOTE: I am using Windows 10 with Internet Explorer 11, ver. 11.212.10586.0, update versions 11.0.30 (KB3148198). One thing I don't really understand is this--I thought Flash was incorporated into Internet Explorer 11. For that reason, I also thought Flash was something which I would not have to update; that it (1) was not a standalone program, and (2) was updated automatically by either Microsoft and/or Adobe if IE11 is installed. If that is wrong, please correct me.
One final point: I think Norton Security may not have taken action against this threat until this morning. That is to say, I did not see Norton Security's File Insight info until this morning--I saw the "update notification" last night, roughly 8 hours earlier.
Question: If this was a real threat, was it a "cookie" type threat? I did not download a file. I wonder if it was a "cookie," because I see the [1] in brackets after the file name (flashplayer[1].exe). Again, I did not download a file--at least, not to my knowledge!
Thanks very much!
Here's a screen shot of the "update notification" I received:
And here is the action Norton Security took (Norton Security 22.6.0.142):
