Viruses are codes or programs that are installed or moved in to your computer without you knowing and allowing it.
A virus can multiply itself and reproduce itself through other files and programs.
Even a tiny virus can multiply and use up all your computer memory and eventually shut down your whole system.
A virus can enter by a USB, download from the web, and other sources.
A dangerous virus can pass through your computer security and anti virus programs.
