uninstall it -and hope chrome keeps up to date
As google chrome builds flash in, if you have chrome, you have to rely on google to keep it up date.
and if you do have chrome installed, then every other browser you have are just going to have to learn that flash is uninstalled. Just do it! One walk round a house cutting it from 3 laptops and 2 desktops and my life is better. I don't have to worry about these 0-days, just despair at Adobe's eternal insecurity.
