Homeland Security has issued a bulletin recommending that QuickTime be removed from Windows PCs. QuickTime has been confirmed to have critical security vulnerabilities, which Apple has made clear will not be fixed as they are dropping support for QuickTime.
Not sure if you have QuickTime installed? If you’ve installed iTunes, you probably do, as QuickTime was often bundled with iTunes installations and updates. An example of the logo is above.
Because of the high profile of this security vulnerability and the lack of support for the product, I would suggest you do go ahead and uninstall QuickTime. You can do this through Add/Remove programs; and as usual, if you have any questions or problems removing it please let me know, and I will be happy to assist
*** Update ***
There is one caveat for folks who use Adobe’s Creative Cloud products to edit videos: apparently, there are apparently some codecs that remain dependent on QuickTime being installed. If you are using Creative Cloud to edit videos, this may be an important consideration. You may want to consider the pros and cons of removing it if this is your situation, or do your design work on a Mac for the time being.
