A method of scripting (controlling) certain functions in a web page, used only by Microsoft Internet Explorer.

Code that, when embedded in a message, may be used to perform potentially damaging tasks unauthorized by the user. trimMail Inbox disables it.

ActiveX controls are elements that can be added to Web pages to give them greater functionality (animation, video, three-dimensional browsing, etc). They are written in a programming language (Visual Basic, C or C++) different from that of Web pages (HTML) and may be infected with malicious code. These embedded objects are run automatically upon viewing web pages containing them. However it is possible to change the browser's security settings to "high" to prevent ActiveX from running. To remove Active X objects containing malicious code they must be deleted.

Programming language and software component model used to connect applications in a network. Active-X was developed by Microsoft and is used by Internet Explorer (among others) to display Office documents. Today, Active-X elements work differently than they did in the past with Windows and now conform to the .com-standard. They may present a security risk, owing to their close relationship with the operating system. Hence, browsers other than Microsoft Explorer do not support Active-X for security reasons.

A proprietary Microsoft technology for building more powerful web pages and web applications.

Since most web pages are static documents with little interactivity, Microsoft created a programming language, called ActiveX, to remedy this situation. ActiveX "controls" promise to make the web-surfing experience comparable to that of highly produced CD-ROMS, where you can listen to music, watch animation and video clips, and interact with the program.
