What is a Computer Virus? A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document.
Viruses will also spread to nearby cells and begin the process again. The human body does have some natural defenses against a virus. A cell can initiate RNA interference when it detects viral infection, which works by decreasing the influence of the virus's genetic material in relation to the cell's usual material.nd some viruses, such as HIV, work essentially by tricking the immune system. Viruses cause many diseases, including colds, measles, chicken pox, HPV, herpes, rabies, SARS and the flu. Though they're small, they pack a big punch -- and they can only sometimes be sent into exile. Launch Video Body Invaders: Virus.
