Internet Worm

What is an Internet Worm?

An Internet Worm is a type of malware that replicates itself (often quite rapidly) across local networks or the internet simply by using communication between computers. Unlike viruses, they do not require a carrier file or program. Some worms can open a backdoor on a computer allowing hackers to take control and create a zombie system.

How to Recognize This Threat: Worms often initially enter a system as an email attachment. An infected computer will then have performance issues, with worms clogging up memory and automatically sending themselves to contacts far and wide.

How to Prevent This Threat: As with any malware, responsible users should avoid opening suspicious files. Comprehensive detection and protection is the key to preventing worms from causing problems on your network.
