where is adobe flash player in my computer?

I'm using Windows 10 with Firefox 42  since a few days and I can't find Adobe Flash Player anymore ( with Windows 8 I knew where it was and I was able to update it). But now, I've checked on Adobe site if I had it and he told me I had it on my computer and it seems I can watch videos but when I search in downloads or programs files or even in c:\Users\me\AppData\Roaming\Macromedia\FlashPlayer, I can't find it. So please where can I find it? I have MacAfee installed on my desktop and find it in program files. I've also checked Adobe Shockwave (19.0 r0) and it's enabled.

Sorry for my english, I'm french. I hope you'll understand what I've written. And thank you in advance to anyone who may answer me!
