Computer worms are malicious programs that spread from one computer to another without user intervention, potentially damaging infected devices. Worms can affect other devices on the same network and even those remotely connected. This article discusses what worms are, how they work, common symptoms of infection, and methods for prevention and defense. Key steps include applying all security updates and maintaining antivirus software to protect against known and unknown vulnerabilities.

send unsolicited email messages (spam) and open backdoors on
infected computers so they can be remotely controlled by an
