Abstract

The invention relates to a device and a method for removing viruses of computer documents. The device for removing the viruses of the computer documents comprises a memory, a scanning module and a replacing module; the memory is used for storing feature codes of known viruses in advance; the scanning module is used for scanning the computer documents to determine whether virus codes are contained in the computer documents or not according to the feature codes of the viruses; the replacing module is used for replacing the virus codes in the computer documents by safe codes when the virus codes are scanned by the scanning module. The device and the method have the advantages that the virus codes in the computer documents are replaced by the safe codes when scanned by the scanning module, so that a computer document repair success rate can be increased, and a computer device can assuredly safely and reliably run.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a virus removal device and method for computer documents. Background technique [0002] At present, most of the user's computers store a large number of documents, such as word documents, excel sheets, etc., and these documents usually store very important information of the user. When a user's computer is infected by a destructive virus, such as a macro virus, these documents, such as office documents, are usually also injected with malicious scripts such as a macro virus. If a user runs an office document infected by a macro virus, malicious scripts such as the macro virus will be executed, causing the computer to perform abnormal actions, such as automatically logging in to a malicious website, deleting documents stored on the computer, etc., thereby threatening the user's security. Computer security has caused huge losses to the user's spirit and property. [0003...
