The warnings both from Trend Micro and the Department of Homeland Security come as Trend Micro discover two new critical vulnerabilities within the software that could be used by remote attackers to gain control of your system. While there aren’t any active attacks targeting this problem, both groups are recommending you uninstall the software from your windows system as Apple will no longer release security updates for QuickTime on windows.
The options seem pretty clear-cut, uninstall some software or risk being exposed to a threat that will never get fixed. While QuickTime on Mac’s is unaffected, Windows users should look to use some of the alternative options available for them if you want to watch media content on your PC.
For information on how to uninstall QuickTime, you can visit Apple’s support page here.
