You should Uninstall QuickTime for Windows with its critical flaws
Uninstall QuickTime for Windows immediately. Apple has stopped updating the product, there are a ton of issues with the program that are being exploited to infect computers, and anyone who has installed an Apple product on their Windows computer (iTunes, iCloud, etc) probably has it even if you never used it.
Yet another program is joining Java, Flash, and Windows XP as big-name software you do not want running on your PC. Security firm Trend Micro and the U.S. Department of Homeland Security are advising all Windows users to uninstall Apple’s QuickTime as soon as possible. (The advisory does not affect Mac users.)
The reason for getting rid of QuickTime for Windows is twofold. First, Apple told Trend Micro it is deprecating the software and will no longer deliver security updates for it. Second, there are two known critical vulnerabilities that could allow an attacker to take control of a system running QuickTime.
That’s a hellacious combo.
Apple was unavailable for comment at this writing, but a quick look at QuickTime’s download page shows the software is still publicly available. It hasn’t been updated since at least January, however.
