What is computer worm and examples?
A computer worm is a malicious piece of software that replicates itself from one computer to another with the goal of overtaking the entire network of computers. Most worms are designed to infiltrate systems by exploiting their security failures, while very few also try to change the system settings.
What is worms and virus in computer?
Virus vs Worm 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.
Is worm in computer dangerous?
Computer worms are among the most common types of malware. They spread over computer networks by exploiting operating system vulnerabilities. Worms typically cause harm to their host networks by consuming bandwidth and overloading web servers. Computer worms can also contain “payloads” that damage host computers.
Why is it called a computer worm?
Description: It fits the description of a computer virus in many ways. For example, it can also self-replicate itself and spread across networks. That is why worms are often referred to as viruses also.
Which is the example of worms?

What is computer virus example?
Examples of computer viruses Worms – A worm is a type of virus that, unlike traditional viruses, usually does not require the action of a user to spread from device to device. Trojans – As in the myth, a Trojan is a virus that hides within a legitimate-seeming program to spread itself across networks or devices.
What is the example of worms?
Is computer worm A virus?
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.
What is a computer worm and how does it work?
A computer worm is a type of malware that spreads copies of itself from computer to computer. It can replicate itself without any human interaction and does not need to attach itself to a software program in order to cause damage.
What is the definition of a worm virus?
Before diving into the definition of a worm, we should define the term computer virus. A computer virus is a carefully hidden piece of computer code that has the ability to spread from one system to another. A virus can do significant damage, or at least it may become a nuisance and interrupt productivity.
What does it mean to download a worm on the Internet?
To help hide the infection, the malicious program is usually a ‘downloader’ – a very small program that later connects to a remote computer over the internet to download a more substantial piece of malicious software. A good anti-virus program can protect you to some extent, but it’s not enough on its own as it’s hard to keep it up to date.
Why is it important to know about worms?
Because worms exploit vulnerabilities in a computer’s operating system, a successful infection can offer unparalleled access to the compromised machine’s inner workings.
