A computer virus is a malicious piece of computer code designed to spread from device to device. Viruses are harmful and can destroy data, slow down system resources, and log keystrokes. A worm virus is a malicious, self-replicating program that can spread throughout a network without human assistance. It often uses a computer network to spread itself, relying on security failures on the target computer to access it A worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program but can run independently and actively carry out attacks. A worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program but can run independently and actively carry out attacks. So, we can say that a Worm is a special type of Computer Virus that fills a computer system with self-replicating information, clogging the system so that its operations are slowed or stopped. Additional InformationIn computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A €œkeystroke€ is just any interaction you make with a button on your keyboard. Each keystroke transmits a signal that tells your computer programs what you want them to do. A zombie computer refers to any device that has been compromised by a virus or hacker.
