Computer viruses are like flu viruses in the real world. Computer viruses are designed to clone themselves and copy them from one computer to another. Computer viruses spread to other computers through a file or document.
Simply, a computer virus is a software or program that is created or written to harm a computer. It attaches itself to files and documents on the infected computer, which can easily spread to other computers.

How do computer viruses attack?
Computer virus programmers attach the virus they created to a file or software that makes that file or software open to everyone. The virus spreads to different computers through that file or software. The computer virus enters the computer but cannot start its work. It has to wait until the user runs the affected software or file. As soon as the affected file runs, the virus starts working on its own. When the virus is executed on a computer, it attaches itself to various files on that computer, so that it spreads through those files as well. Some viruses can even spread to other computers on the affected computer’s network.
