Internet Explorer has started blocking out-of-date ActiveX controls from from August 12, according to Microsoft.
ActiveX controls are small apps that let websites provide content, like videos and games, and let users interact with content like toolbars. ActiveX controls are not automatically updated; they can become outdated as new versions are released.
It is very important for users to keep their ActiveX controls up-to-date because malicious or compromised Web pages can target security flaws in outdated controls to collect information, install dangerous software, or by let someone else control your computer remotely, Microsoft advised.
Out-of-date ActiveX control blocking will operate to let you know when Internet Explorer prevents a Web page from loading common, but outdated, ActiveX controls. It will interact with other parts of the Web page that are not affected by the outdated control and update the outdated control to make it up-to-date and safer to use.
