Abstract
A malicious driver replacement application is installed on a host computer system and registered as a boot execute application. On notification of a malicious driver detection, the malicious driver replacement application reboots the host computer system and locks the volume of a storage disk containing the malicious driver. The malicious driver is replaced directly on the storage disk with a dummy driver having innocuous code. The malicious driver replacement application reboots the host computer system, and on reboot of the host computer system, the dummy driver is loaded rather than the malicious driver thus preventing the malicious driver from interfering with the standard operating system routines and allowing the malicious driver to be remediated.
