A worm is a type of malware that can spread from one computer to another without any user interaction. It does this by exploiting vulnerabilities in software and operating systems. Once a worm infects a computer, it can replicate itself and spread to other computers on the same network. Worms can cause a variety of damage, including deleting files, stealing data, and disrupting network traffic.
Worms are a serious threat to computer security, and it is important to take steps to protect your computer from infection. These steps include keeping your software and operating system up to date, using a firewall and anti-virus software, and being careful about opening email attachments and clicking on links from unknown senders.
