Compromised boot drivers can introduce malware prior to some protection mechanisms that load after initialization. The Early Launch Antimalware driver can limit allowed drivers based on classifications determined by the malware protection application. At a minimum, drivers determined to be bad must not be allowed.

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.
