We’re not aware of any active attacks against these vulnerabilities currently.But the only way to protect your Windows systems from potential attacks against these or other vulnerabilities in Apple Quick Time now is to uninstall it.
They will no longer be issuing security updates for the product on the Windows Platform and recommend users uninstall it.
This method will probably take at least three or four hours and you will have to redo all custom settings you have in Windows and in the main programs you use.
The advantage of this method is that it will take care of all software problems you may be having and your computer will run faster at the end.
After you have done this, future updates will be installed automatically Hmm..did not work that way when I installed the Trial on 5270.
So after trying my previous Trial and that didn't work, registering again under a different email, waiting for the email, uninstalling the old one, downloading and installing the new one, etc.
