Trend Micro has announced two critical security vulnerabilities in Apple’s Quicktime for Windows. At this time it would be wise to remove any version of Quicktime from computers in a Windows operating system environment until a patch is available. There appears to be rumours of Apple advising that support for Quicktime on the Windows platform has been dropped; but for now Apple has yet to comment on the matter.
If you are apt to be safe than sorry, you can find the Quicktime uninstaller in the Programs and Features menu on current Windows platforms. Highlight the application and look for the ‘uninstall’ button near the top of the window.
