The invention provides an anti-virus device and method for real-time monitoring of files in a computer. In virus library or engine update, users are ensured having good experience, and safety of the computer is also ensured. The device for real-time file monitoring and anti-virus comprises an application layer part and an operation system core part. The application layer part includes a logical module for file system interactive processing and an application programming interface (API) module provided by the operation system and applied for the file system; and the operation system core part comprises an anti-virus software file system driving module for intercepting file operation and a file system driving module for actual operation system. When the updating operation requires replacement of engines and virus libraries, the device is provided with two anti-virus software application layers, and each anti-virus software application layer comprises an anti-virus engine and a virus library, i. e. the device is provided with two anti-virus engines: anti-virus engine 1 and anti-virus engine 2; and two virus libraries: virus library 1 and virus library 2.
Description
technical field [0001] The invention relates to computer virus prevention technology, in particular to a computer virus prevention device and method capable of real-time monitoring of files. Background technique [0002] With the development of computer technology, there are more and more types and hazards of computer viruses, which cause hardware damage, data loss, or abnormal use, etc., which have brought great impact and losses to computer users. Computer viruses are highly contagious and contagious, and are mainly spread through the network or by infecting executable programs in computers. At present, antivirus software is mostly used to detect and kill computer viruses. Antivirus software generally consists of a virus inspection engine and a virus signature database. The virus checking engine checks the computer files according to the virus signature codes in the virus signature database, and checks the files under computer coordination. If a corresponding signature co...
