Antivirus and virus-killing mp3 device and method for preventing and killing virus thereof

Abstract

The invention provides a defending and killing virus mp3 device and a method for defending and killing virus. The device comprises an mp3 main control chip, a CD-ROM zone, an encrypting zone and a common memory area, the method comprises: inserting the device into a computer, then, indentifying through a computer system, decompressing an antivirus program and a virus library compressed packet to an appointed folder on a computer harddisk, operating the antivirus program, detecting whether a new virus library is available or not through the antivirus program, updating if the new virus library is available, controlling the virus library to automatically write back to a program in the encrypting zone to operate after updating, writing a newly updated virus library file back to the encrypting zone, operating the antivirus program, checking and killing computer virus, monitoring the computer harddisk and the defending and killing virus mp3 device on real time, extracting the defending and killing virus mp3 device after finishing checking and killing the virus, and deleting the antivirus program from the computer harddisk automatically. The invention can effectively prevent and kill the virus and monitor the harddisk and U disks, and can use the defending and killing virus mp3 on the computer which is provided with antivirus software already without collisions.

Description

Technical field [0001] The invention relates to an mp3 player, in particular to an mp3 anti-virus device used for monitoring and killing computer viruses and capable of realizing the upgrade of its own virus database and its anti-virus and anti-virus methods. Background technique [0002] At present, the prevention and detection of computer viruses is generally achieved by installing anti-virus software on the computer hard disk. This method can also implement virus monitoring on the computer’s hard disk and regularly upgrade the virus database, but the anti-virus software It can only be installed on a computer, it is not convenient to carry, and the anti-virus software and virus inventory are at risk of being destroyed. In addition, nowadays, viruses are flooding on computer networks. Often after installing a kind of anti-virus software, the computer will be severely infected by the virus, and even the anti-virus software can’t be started and damaged by the virus, and two types ...

Problems solved by technology

[0002] At present, the prevention and killing of computer viruses is generally achieved by installing anti-virus software on the computer hard disk. This method can also implement virus monitoring on the hard disk in the computer at the same time, and regularly upgrade the virus database. However, the anti-virus software It can only be installed on a computer, which is inconvenient to carry, and there is a risk of damage to the antivirus software and virus library

In addition, viruses are rampant on the computer network now. Often after installing an anti-virus software, the computer will be severely infected by the virus, and even the anti-virus software cannot be started or damaged by the virus. Anti-virus software is likely to cause conflicts, causing the computer to run slowly, or not to start normally, etc.
