ActiveX controls are Internet Explorer’s version of plug-ins.

For example, Internet Explorer’s Flash player is an ActiveX control.

Unfortunately, ActiveX controls have been a significant source of security problems.

ActiveX controls are like other programs – they aren’t restricted from doing bad things with your gear.

ActiveX controls are actually not Internet Explorer-only.

They also work in other Microsoft applications, such as Microsoft Office.
