You probably know that Microsoft is no longer updating Internet Explorer, in favor of Microsoft Edge.
But switching to another browser is not just a matter of preference, it's also a matter of security.
Even Microsoft warned in March that using Internet Explorer as a default browser was perilous. Many apps are designed for IE but new apps and Websites are not. So new Websites won't even work with IE.
Now, according to the blog, HotforSecurity, an IE user who opens an .MHT attachment (an archive of a Web page) can let hackers into their system. Even opening a Web page archive you have made can do the same thing.
Only about 7 percent of desktop browsers still use Internet Explorer, but the app is usually installed on a Windows system.
Security experts recommend completely uninstalling Internet Explorer through the control panel.
