what  is   viruses cannot do
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.
This all depends on the virus. If programmed correctly, they can do almost anything. They cannot, as far as I know, rewrite the ROM in your computer or removable devices. Thisâ¦ must be infected manually. It is also unlikely that they can cause your power supply to over produce, or your hard drive to excelerate to the point of destruction.
