Uninstall "Internet Explorer Plugins"
Internet Explorer offers several ways in which other programs can change it's behavior and improve it's features. For example, Internet Explorer can not, by itself, display highly animated web sites. But, because Internet Explorer can be extended, another company called Macromedia has created an extension plug-in called Flash, which can display multimedia web sites. Many other enhancements, like download managers, etc, are also available.
