Trojans, Viruses and Other Computer Security Threats
What is a computer virus? What is the difference between a virus and a worm? Let's find out more about Trojans, Viruses and Other Computer Security Threats.
What is a computer virus?
Term "trojan virus" is not technically accurate; according to most definitions, trojans are not viruses.

What is the difference between a virus and a worm?
Most common types of malware are viruses, worms, Trojans, bots, ransomware, backdoors, spyware, and adware. Damage from malware can vary from causing minor irritation (such as browser popup ads), to stealing confidential information or money, destroying data, and compromising and/or entirely disabling systems and networks.
Viruses: These are small pieces of code that can cause serious harm to computer systems. They are often spread through the internet and can be downloaded onto computers by means such as email. Once on a computer, a virus can start to spread its feces by self-replicating and entering other computers' files. It is important to be vigilant about protecting your computer systems against viruses because they are very dangerous.
Worms: Worms are large pieces of code that can damage or disable systems. They can also be used to spread viruses and other malicious software. Worms vary in size from a few hundred bytes to almost 20 MB. When they detect a new program or file, they will create a worm document that refers you to the worms' creator website. From there, you will need to install the worm on your computer in order for it to start working.
