ActiveX is an extension to Microsoft's OLE (Object Linking and Embedding) and COM (Component Object Model) technologies used in applications and on the Internet. Using ActiveX, an Internet browser can interact with your computer more than what is available through HTML (hypertext markup language). For example, ActiveX allows users to scan their computer for viruses in their browser using free online antivirus scanners or scan their computer for any Windows updates.

Although there are benefits to using ActiveX, there are known security threats and malware that use ActiveX because it can interface outside the browser. Therefore, unless you know what the ActiveX plug-in does and trust the website, we recommend not installing any ActiveX plug-ins.

Microsoft Internet Explorer is the only Internet browser that uses ActiveX, although many alternative browsers do have ActiveX plug-ins. Browsers that do not support ActiveX use alternative plug-ins such as Flash, Java, and Shockwave or use other technologies like JavaScript and HTML5.
