Cheyenne AntiVirus Guide [antikvár]

Computer Viruses: An Overview Similar to a biological virus, a computer virus is a small program that infects j/owr computer. The basic characteristics of computer viruses are self-replication and file attachment. Viruses are not intelligent. They are usually a set of instructional codes to perform a particular function. Some viruses are very complex, like the polymorphic type. This type of virus can replicate itself a bit different each time, so that the newly born viruses are actually a mutant variation of the original. A virus may be designed to wipe out your CMOS information, reformat your data on the hard drive, or simply replicate itself so many times that you will not be able to access the data that you stored on the computer. Typical viruses are usually very small executable programs that attach themselves to another program. They are usually designed to be stealthy, and destructive. So why do you need protection from these viruses? A virus, at best, is a nuisance to your system, displaying some obscure texts or graphics on your monitor.
