MailSafi Glossary of Terms
A type of malware that spreads itself from computer to computer without the aid of any human interaction. Unlike computer viruses, worms do not need to attach themselves to software files/programs in order to cause damage. They exist as separate standalone programs.
Additionally, unlike computer viruses, worms do not alter files. They reside in active system memory and replicate. They use parts of the operating system that are invisible to the user and consume system resources that lead to significant slowing down of systems or halting of tasks entirely.
Worms are also transmitted via email spam. Investing in a good anti-spam solution will minimize the risk that your computer system will be infected by a worm.
