What is a virus?
A virus is an obligate intracellular parasitic acellularmicroorganism, consisting of protein coat and nucleic acid DNA orRNA and may be enveloped or not. It is a particle that… is notdefined as being alive, that goes inside you and attacks yourcells, and inserts their DNA into your cell, so that your cellmakes more of the virus instead of making more of itself. If you mean in computers, its when malicious code is running inyour computer and doing damage. Just like a biological virus,computer viruses alter existing code and produce more copies ofitself. But it is just computer code and not anything that isalive. If you have this, you should run antivirus software or gethelp from a computer professional. (MORE)
