Vulnerability discussion

This policy setting determines whether Internet Explorer runs Anti-Malware programs against ActiveX controls, to check if they're safe to load on pages. If you enable this policy setting, Internet Explorer won't check with your Anti-Malware program to see if it's safe to create an instance of the ActiveX control. If you disable this policy setting, Internet Explorer always checks with your Anti-Malware program to see if it's safe to create an instance of the ActiveX control. If you don't configure this policy setting, Internet Explorer won't check with your Anti-Malware program to see if it's safe to create an instance of the ActiveX control. Users can turn this behavior on or off, using Internet Explorer Security settings.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
