" What is a virus?
A virus is computer code that attaches itself to a program or file to spread from one computer to another. It infects as it travels. Viruses can damage your software, hardware and files.
A virus attaches itself to a host program then attempts to spread from one computer to another. It may damage hardware, software or information.
computer viruses range from mildly annoying to the downright destructive. The good news is that a true virus does not spread without human intervention. Someone must share a file or send an email to propagate.
