Computer Viruses
In the past two decades there have been great advances in technology that have reaped immense benefits towards us all. Computers are seen in almost every home and office in today's world. With these powerful machines we have limitless capabilities and with the added power of the Internet, anything that one could ever want is at their fingertips. Information is being transferred between computers at every second in time. However sometimes there are small hidden secrets to these transfers, viruses. Viruses are computer programs that are created to infest and spread to other programs with copies of itself. They are run without the users request and are hidden in the background somewhere. They remain secret and perform their actions; most likely without the user knowing or able to compromise the actions they perform [1]. In a sense you can compare computer viruses to the taunt "Anything you can do I can better". Anything that a legitimate program can do, computer viruses can also do, only secretly [3]. Their behavior is just like that of a real virus, they spread and transfer between computers through networks, the Internet, and storage disks. Not all viruses are considered fatal to your system. S
They do this with programs that contain protection features that will anticipate the next phase of the virus [4]. Once one is on a host computer it can attach itself to other software programs and remain hidden in them. The user will never suspect anything because he/she would normally expect the disk to be read at this time. The infected files individually enter into directories, search quickly, and get out [3]. The user will probably never even notice. This then allows the virus to generate GPI's. Hackers are the most active group developing and sharing the technological wisdom of how viruses work. The GPI's then use a file marker system to infect further files. The bad thing about this virus type is that being it infects unrelated files to search for its destination, those files remain infected after the destination file(s) are removed and restored to work again. As a case in point, the virus may initially contaminate command processors and/or boot sectors. They are not just something that you see on TV or something that you figure will never happen to you; they can infest anyone's system. The best way to guard yourself is with regular backups of your system and by taking extra caution in file exchanges.
