I too had a warning about flash not being up to date while I was looking for some news clips a few days ago, I ended up closing the window as I didn't trust getting what is described as critical system updates from a web site instead of through my usual Windows Updates, I didn't think it was something that I need worry about but little did I know at the time. I'll check all the PCs at home to ensure that they have the latest versions of flash or maybe even remove flash completely as has been suggested above.
