ActiveX controls are essentially mini-programs that can be shared by different Windows applications. For example, Internet Explorer is not able to display PDFs or show Flash animation by itself, but it can do so by executing the proper ActiveX controls. Unfortunately, ActiveX controls are so easy to design and implement that they are one of the most common tools for loading viruses, spyware and other malicious software onto people’s computers. Because of this, every time a website tries to install an ActiveX control, Internet Explorer asks you whether you want to allow it. These prompts can prevent harm to your computer, but they can also be annoying when you are on trusted sites. You can stop the prompt for ActiveX controls by changing your computer’s security settings. Tips Warnings Writer Bio
