A computer virus is malicious code that replicates by copying itself to
another program, computer boot sector or document and changes
how a computer works. The virus requires someone to knowingly or
unknowingly spread the infection without the knowledge or
permission of a user or system administrator.
In contrast, a computer worm is stand-alone programming that does
not need to copy itself to a host program or require human interaction
to spread. Viruses and worms may also be referred to as malware.
