Embodiments of the present application provide a method and apparatus for removing a root-privileged virus and an electronic device. The method includes: scanning the smart device to find a root-privileged virus file; obtaining a root-privileged removing process according to the virus file; and removing the root-privileged virus file according to a preset removing strategy by using the root-privileged removing process. As a root-privileged process is directly obtained in this embodiment by using a found virus file, the smart device can obtain the root privileges more quickly, improving the speed of killing the root-privileged virus.
