Re Adobe Flash Updates: See this link for off-line Adobe Flash Installer http://www.adobe.com/products/flashplayer/distribution3.html
Anytime you see a request to upgrade, check here. BTW, using an offline installer is always safer as long as it is known to be at the Adobe website.
Personally, only use Google Chrome to view streaming video as that comes with an up-to-date Flash player and do not have either IE or FF running flash.
