What are Malware & Viruses

Two common types of malware are viruses and worms. These types of programs have in common that they are both able to self-replicate; they can spread (possibly modified) copies of themselves. Not every program that copies itself is a virus or worm; for instance, backup software may copy itself to other media as part of a system backup. To be classified as a virus or worm, at least some of these copies have to be able to replicate themselves too, such that the virus or worm can propagate itself. The difference between a virus and a worm is that a worm operates more or less independently of other files, whereas a virus depends on hosts to spread itself.


Malware (a portmanteau of "malicious software") is software program designed to fulfil any purpose contrary to the interests of the person running it. Examples of malware include viruses and trojan horses.

Malware can be classified based on how it is executed, how it spreads, and/or what it does. The classification is not perfect, however, in the sense that the groups often overlap and the difference is not always obvious, giving rise to frequent topic discussions.


In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents made by crackers (for a complete definition: see below). A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells.
