What is ActiveX Control? How it works? What are the risks?

ActiveX controls are the program, sometimes also called "Add-on" that are used on the Internet. They can enhance your browsing experience by allowing animation or they can help with tasks such as animation etc.

ActiveX controls and web browser add-ons are small programs that are used extensively on the Internet. They can make browsing more enjoyable by providing toolbars, stock tickers, video, animated content, and more. These programs can malfunction, however, or give you content you don't want. In some cases, these programs can be used to collect information from your computer in ways you might not approve of, possibly damage information on your computer, install software on your computer without your consent, or allow someone else to control your computer remotely. Given these risks, you should only install ActiveX controls or add-ons if you completely trust the publisher and the website offering it.

Some websites require you to install ActiveX controls to see the site or perform certain tasks on it. When you visit such a site, Internet explorer asks if you want to install the ActiveX control.

The website that provides the ActiveX control should tell you what the control is for , It should also provide relevant details on the page before or after uou see the warning. Internet Explorer blocks websites from using and ActiveX control on your computer if the website tries to use the ActiveX control in a way that might not be safe.

What are the risks?

Unfortunately, ActiveX controls are like any other software program-- they can be misused. They can stop your computer from functioning correctly, collect your browsing habits and personal information without your knowledge, or can give you content, like Popup ads that you dont want. Also, good ActiveX controls might contain unintended code that allows bad websites to use them for malicious purposes.

Note:- If an ActiveX control is not essential to your computer activity, avoid installing it.
