Adobe Flash exploits... still?
You can understand an operating system requiring a steady stream of security updates over time - it's big and clunky with large chunks of code not revised for many years and written before the idea of exploits really took force.
But Flash? Every bloody month there's some new and exciting vulnerability discovered. It's 0.001% the size of an OS yet it seems to have more vulnerabilities than Windows and OSX put together. Not only that but it's got a crap updater that doesn't follow any style or usability guidelines laid down by Microsoft - hardly surprising it's ignored.
Come on Adobe - (a) consider rewriting it from scratch or open sourcing it and (b) integrate it into Windows updates so that fixes are delivered seamlessly.
