*Applies to QuickTime on Windows, not on Mac OSX
According to a recent alert published by US-CERT (US Computer Emergency Readiness Team):
Computer systems running unsupported software are exposed to elevated cybersecurity dangers, such as increased risks of malicious attacks or electronic data loss. Exploitation of QuickTime for Windows vulnerabilities could allow remote attackers to take control of affected systems.
Bottom line: Some may remember a time when Apple iTunes required users to have QuickTime installed on their computers, however, this is no longer the case. In fact, most modern systems do not require QuickTime. These two serious vulnerabilities, which leave the system open to exploitation, are never going to be fixed and the best solution is to uninstall QuickTime as soon as possible.
To remove QuickTime follow these steps:
- Windows Vista and 7 users: Go to Start > Control Panel > Programs > Programs and Features, then double-click on QuickTime
- Windows 8.1 and 10 users: Right click on the Start button and select Control Panel, then follow the same steps as above
