Abstract: Embodiments of the present application disclose a method and apparatus for removing a root-privileged virus, and an electronic device. The method comprises: detecting, according to a preset virus database, whether a smart device has a file with a characteristic of a root-privileged virus; obtaining a system root privilege when a file with the characteristic of the root-privileged virus is detected; terminating all processes corresponding to all the detected files with the characteristic of the root-privileged virus; recovering system startup items to a status before the intrusion of the root-privileged virus; and deleting all the detected files with the characteristic of the root-privileged virus. Compared with the prior art, the embodiments of the present application enable root-privileged viruses to be killed more thoroughly.

Abstract: 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.

Abstract: 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 (S101); obtaining a root-privileged removing process according to the virus file (S102); and removing the root-privileged virus file according to a preset removing strategy by using the root-privileged removing process (S103).
