Abstract
Provided are a method and system for repairing a file at user terminal. The method comprises: scanning a file at user terminal, determining whether the file is abnormal, and acquiring file characteristics information; if the file is abnormal, then according to the file characteristics information, acquiring from a cloud server a secure file corresponding to the abnormal file and uploaded before abnormity occurring, wherein the secure file in the cloud server is acquired by directly uploading file of user terminal; and replacing the corresponding abnormal file of the user terminal with the secure file. The method and system save the secure files of each user terminal in a cloud server, and when an abnormal file occurs in the user terminal, download the secure version of a corresponding file from the cloud server to replace the local abnormal file, thus ensuring recovery of the correct version of the file into the system, and solving the problems that the abnormal file cannot be restored to normal status during the conventional file repair process or cannot be repaired due to complexities caused by virus infection.
