Some Research on computer viruses Invasion and PreventionAbstract:With the continuous progress of science and technology popularization of computers, and its getting higher and higher utilization, more and more wide applications.
Computer network system as a unit has become more human beings to build the most colorful of the virtual world, the birth of computer networks and development, to our day-to-day life
of work and learning has brought about tremendous change. Our access to information through the network, the sharing of resources. However, the emergence of the computer is also a double-edged sword, bring happiness to the people but at the same time meet with the computer join the network and computer security system has been an increasing number of threats. Computer's stability and security has also been concerned about the growing number of people. Loopholes in the current computer systems have been found that viruses and hacking skills and ability to continuously improve the damage, in the computer network has been an increasing number of attacks. Every day tens of thousands of viruses, worms, Trojans, spam on the network communication, network blockage or interruption, destruction or loss of personal computer systems and other important information; these new blended threats increasingly to individuals and businesses have resulted in huge loss, and the above-mentioned threats, the traditional way will not be able to effectively prevent violations of the dynamic virus. The increasing complexity of the network, diversity of today, the dynamics of how to effectively protect your computer applications, not to be malicious information attacks viruses have already caused great concern in society.
In order to strengthen the defensive capabilities of the current computer, we need to in-depth study of the virus from entering the path of computer systems, and how these path corresponding to the implementation of prevention and treatment means. This carried out in accordance with the path control block-style thinking is the most appropriate idea of the computer system security. The depth of this line of thinking for the protection of computer reliability and integrity of the operation has a very important significance.
