Abstract

The invention relates to an anti-virus device arranged between a computer and a network device and an anti-virus method. The anti-virus device (1) temporarily stores data transmitted between the computer and the network device in a data temporary storage region (102) and performs virus filtration operations on the temporarily stored data in the data temporary storage region (102) so as to find out whether the temporarily stored data contain data according with any one virus feature code (2) in the data temporary storage region; and when the temporarily stored data are detected to have a feature according with any one virus feature code (2) therein, the anti-virus device intercepts the temporarily stored data so that the temporarily stored data with the virus feature cannot pass through the anti-virus device (1) and be transmitted to a destination. The anti-virus device (1) is independent from an operating system of the computer and is an independent hardware device, which can continuously perform the virus filtration on the data transmitted between the computer and the network device without interferences even when the operating system has a loophole and is attacked by viruses.

Description

【Technical field】 [0001] The invention relates to the technical field of computer data security, in particular to an antivirus device and method arranged between a computer and network equipment. 【Background technique】 [0002] With the rapid development of computer technology, computers have become one of the necessary tools for people's daily work, but the emergence of computer viruses has interfered with people's work using computers. At present, most computer viruses are contagious, especially viruses that spread through the network. It can infect other computers on the network through the network in a very short time. These computers infected with viruses can have a serious impact on computer users, and the data stored in the computers by users will be destroyed by viruses at any time, causing incalculable losses to users, which is an extremely problem to be solved. 【Content of invention】 [0003] The purpose of the present invention is to provide a computer anti-vir...
