Virus (in biology) refers to microorganism, means very small creatures. Likewise, virus is a small sized program in computer world but can cause severe destructive actions to computer(s). Virus can result in poor performance, loss of data, loopholes in system. Because of it, everyone who uses computers have a fear of losing data.
