This causes the targeted AV software not to be loaded after the system restores, enabling the malware to execute without disturbance.\r\n\r\nThe driver performs this action because the user-mode code can\u00e2\u20ac\u2122t overwrite AV registry data; it employs self-protections to prevent exactly that. However, when executed by a driver, which can carry out more actions on a deeper privilege level, it is much harder to prevent such actions."
