I am always advising you to update the software that you use with the latest security patches and updates because cybercriminals exploit newly discovered vulnerabilities in the software programs that we all use to deliver malware such as ransomware and keystroke logging malware that can steal the information from your computer and use it to make you a victim of identity theft. Too often, criminals are successful in using malware against which there are already issued security patches, but that many people fail to install in a timely fashion. It is for this reason that I am constantly providing you with the latest security updates as issued by the Department of Homeland Security.
However, sometimes when it becomes just too difficult to plug the holes in particular software, the software maker will abandon the particular software and not issue any further updates. This was the case with the Windows XP operating system. Continuing to use that system puts you in significant danger of being hacked. Now, Apple has announced that it will no longer produce security updates for its QuickTime media player which handles video, audio and interactive content. This is a major announcement and if Apple is abandoning QuickTime, so should you.
The risk of continued use of QuickTime is too great. Not only should you cease to use it, you should also uninstall it. Here is a link to Apple’s instructions for uninstalling QuickTime. https://support.apple.com/en-us/HT205771
Here also is a link to the announcement by the Department of Homeland Security about Apple ending its support for QuickTime for Windows. https://www.us-cert.gov/ncas/alerts/TA16-105A
Also, in keeping with my advice to update your computer software programs with the latest patches as soon as they become available, here are links from the Department of Homeland Security to important updates for Microsoft software and Google Chrome.
