Computer has really provided all of its users with overwhelming benefits during their accomplishment of certain computing activities. Before the widespread implementation of computer, people have to implement various manual instruments to streamline their endeavors. When they want to make a written document, they have to use their own hand or typewriter. Computer eases such writing activity by providing writers with the spell check and grammar check capability that cannot be provided by traditional typewriters, either the manual or electronic ones. When people need to create a spreadsheet, before the implementation of computer, they can only depend on paper, pencil and calculator to work their spreadsheet. After the computer assistantship is employed to process their spreadsheet, their job is significantly eased and simplified because most spreadsheet processing applications in the computer have been equipped with integrated mathematical and statistical operation capabilities. There are many more benefits that have been given by computer to all of its users.

However, such benefits do not come for free. It has been a common belief that whenever new revolutionary breakthroughs are invented and they become extensively popular, various malicious activities will emerge and interfere with their accomplishment of their beneficial role. When computer gives benefits to a lot of people from around the world and its implementation quickly receives popular acknowledgement, malicious activities in the form of viruses and spywares emerge to attack all computer systems in the world.

Such threats become much more dangerous when all computers in the world are connected by internet. Computer users from around the world are not only exchanging data among them, but also malwares which are concealed among those exchanged data. Therefore, it is recommended that every computer owner protects their computer with a reliable and unceasingly updated antivirus to prevent their computer from being infected by any of those malwares.
