Since the 21st century， the human economy has developed high speed， the people live have had the change which changes with each new day， specially computer's application and popularization to economical and social life each Along with the computer in the social life each domain's widespread utilization， the computer virus attack and the guard technology unceasingly is also developing， has brought the huge destruction and the latent threat for the computer It is reported that various countries suffer the computer virus infection and the attack event are counted by the 100 million， has disturbed the normal human society life seriously， has brought the huge latent threat and the destruction for the computer network and the Along with the computer， the network utilization popularizes unceasingly， thoroughly， will guard against the computer virus to receive various countries to take seriously more and In order to ensure system's security and unimpeded， therefore， studies the computer virus the measure to be This article obtains from computer's characteristic， to come the preliminary discussion to cope with the computer virus the method and the 计算机Computer，、病毒 virus系统安全system safety
Abstract along with computer technology's full scale development， our life as well as the work is day by day In order to cause the management to be more scientific， to be more convenient， is more At the same time， can also help the telecommunication cost concerned personnel to raise the working efficiency and the grade of Reduces the nonessential loss for the telecommunication Thus effective enhances the telecommunication bureau economy the The terminal cost system's development then fast develops， it can realize to the different model program controlled switch the primitive telephone bill information which fixed time or hands down from generation to generation immediately to the cost center carries on prompt accurate classified， the inquiry， the browsing， the revision， the deletion， statistical， the telephone bill information printing and so Can inquire the customer telephone conversation data promptly， avoids causing the phone bill to dispute， enhances the customer the degree of this article by through to the telecommunication bureau cost center routine work's analysis， realized fully based on the management science angle the computer technology development has managed the influence which for the telecommunication bureau brings， in this paper had demonstrated comprehensively used the VB program control to realize the automated cost system's design and to realize in the cost system's immediate cost pattern plate key words: VB cost system
