Still got QuickTime on your Windows computer? Not for much longer, if you value the security of your machine.
After Apple decided it was not going to support the video player anymore, PC security firm TrendMicro sent out a message recommending that any remaining users of the software uninstall it. Why? Because they've identified that there are at least two exploits in the code and since QuickTime will not see any updates this leaves your computer open to potential danger.
TrendMicro identified the two zero-day exploits in the code as part of their services, and it makes use of a heap corruption to allow for remote code execution. Sure, it requires the user to visit compromised websites and because a number of web browsers no longer support the QuickTime plugins you'd need to download and play infected video files, but it's better not to take that chance isn't it?
Apple itself has urged users to uninstall the software from Windows machines, providing a set of uninstall instructions on their site. If you're on Mac OSX though, it's up to you whethere you wish to uninstall or not, as Apple will obviously continue to support their own OS and so any problems can be blocked from the OSX side.
As always though, the best defense against malicious programs online is your own common sense and caution. Knowing when certain programs are acting as doorways is right behind that though in importance.
