TOP 50+ Virus and Worms Quiz and Answers (Cyber Security)

Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another. Because of this, worms can propagate themselves and spread very quickly – not only locally, but have the potential to disrupt systems worldwide.

An important distinction between computer viruses and worms is that viruses require an active host program or an already-infected and active operating system in order for viruses to run, cause damage and infect other executable files or documents, while worms are stand-alone malicious programs that can self-replicate.

Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate.

The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.

Worm is a type of virus that spreads itself, not just from file to file, but from computer to computer via e?mail and other Internet traffic. A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers.
