Update Flash Player pop-up

I keep getting the following pop-up on my mac and after reading about it I saw that there is a Flash Player virus going around. I don't want to update Flash Player and no matter what I do, I can't get rid of the message above. I usually Remind Me Later or Force Quit, if I go to Download, it brings me here, Adobe - Adobe Flash Player Download Is that a legitimate website and is the pop up also legitimate?
How do I get rid of it so it stops popping up? As I said I don't want to update - so I uninstalled Flash Player, I also read to go to my System Preferences and delete the Flash Player Pane, which I also did, it's no longer listed. So what else can I do?
I have never gone through with the download, so I don't believe I have the virus on my computer, but I just can't figure out how to get rid of the pop up.
Thank you!
