You may know about poor security of Microsoft Internet Explorer and now it is really harmful to have it on your PC as you can be attacked by anyone.
According to a security researcher, John Page has identified that Microsoft Internet Explorer is using MHT files that hackers can use to spy Windows users and can steal their data as well.
Since Windows opens MHT files through MHT files by default, therefore, for taking control of a particular PC, you only need to send an attachment through email or chat.
This vulnerable problem only affects Windows 10, Windows Server 2012 R2 and Windows 7.
It is reported that Microsoft was releasing a security fix update but delayed it due to the identification of exploit by John Page.
Probably, the security fix update will be released in the near future. But, the company need to either turn off Internet Explorer or just direct it to another app that utilizes MHT files.
