Problems solved by technology

Due to the continuous emergence of new viruses, anti-virus software needs to constantly update or increase the virus characteristics of the anti-virus software virus database, resulting in frequent upgrades. The problem of viruses is always solved after the virus appears, or even after the disaster. Disastrous consequences such as data loss or system crashes are caused, and even the best anti-virus software is helpless. It can be seen that the existing anti-computer virus methods work in a passive manner, are troublesome to use, and have poor anti-virus effects

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The main target of computer viruses is usually hard disk data. The main hosts of viruses are hard disk files, EMAIL or web pages, and executable codes such as boot records; the hard disk infection targets are mainly executable codes, such as binary codes, macro viruses, and scripts. However, no matter whether it is a macro virus or a script, the operation depends on the binary code to activate;

[0022] Relying on backup can better solve the following problems: all executable codes of the system are backed up. Under normal working conditions, these executable codes should not be changed. If they are changed, it indicates that the system is not running normally.

[0023] Monitor all executable codes on the system hard disk, and you can find some typical problems of the system, such as the length of the executable code sequence or the change of the content, whi...

Abstract

The invention discloses a method for defending itself against computer virus; macro virus, script virus, boot sector virus, partition table virus and document virus. The scheme of defending itself against limited virus for all software and defecing itself against infinite virus for limited software is adopte dthat the scheme prevents computer from virus invading, but is independent of feature codes of viruses. Thus the invented method a avoids burden of frequency upgrade of traditional anti-virus method and can solve virus problem before it presents.

Description

Technical field: [0001] The invention relates to a computer virus defense method. Background technique: [0002] In people's production and life, computer viruses have become an important factor affecting the effect and efficiency of computer use, and the prevention and treatment of computer viruses has become an urgent task in the process of computer use. At the same time, there are many anti-computer virus software on the market. However, the anti-virus methods adopted by current anti-virus software almost all rely on virus signatures. Because computer viruses usually have their own characteristics such as identities, when a computer virus appears, first find the characteristics of the virus, and search and process the virus represented by the characteristics according to the characteristics. Due to the continuous emergence of new viruses, anti-virus software needs to constantly update or increase the virus characteristics of the anti-virus software virus database, result...
