ActiveX controls are small apps that allow websites to provide content such as videos and games. They also let you interact with content like toolbars and stock tickers when you browse the web. However, these apps can sometimes malfunction, or give you content that you don't want. In some cases, these apps might be used to collect info from your PC, damage info on your PC, install software on your PC without your agreement, or let someone else control your PC remotely.
ActiveX Filtering in Internet Explorer prevents sites from installing and using these apps. This can help keep you safer as you browse, but it can also affect the performance of certain sites. For example, when ActiveX Filtering is on, videos, games, and other interactive content might not work.
Internet Explorer might not be set up to download or run ActiveX controls for security reasons. Changing some advanced security settings will let you download, install, or run the control, but your PC might be more vulnerable to security threats. Only change advanced ActiveX settings if you're sure about increasing the level of risk to your PC.
To change ActiveX settings
If you're unable to change ActiveX settings, you might not have permission to and you should check with your system administrator.
