If you use Windows operating system and still have Apple QuickTime media player installed, you should get rid of it, the U.S. Department of Homeland Security (DHS) advises.
Apple issued last update of QuickTime for Windows on Jan. 7 and, according to Trend Micro, there will be no further support.
Since then, two new security flaws were found in the software that would allow hackers to hijack Windows computers with QuickTime if the user opens an infected file or visits a malicious website targeting the flaws.
You can check what programs are installed on your computer, and if you find QuickTime, consider uninstalling it immediately.
