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.
