A virusis a piece of computer code that inserts itself within the code of another standalone program, then forces that program to take malicious action and spread itself.A wormis a standalone piece of malicious software that reproduces itself and spreads from computer to computer.You've probably heard the words virus, trojan, and worm used interchangeably, but as Symantec explains, they describe three subtly different ways malware can infect target computers: There are a number of different ways of categorizing malware the first is by how the malicious software spreads.

As Microsoft puts it, " is a catch-all term to refer to any software designed to cause damage to a single computer, server, or computer network." In other words, software is identified as malware based on its intended use, rather than a particular technique or technology used to build it. Malware, short for malicious software, is a blanket term for viruses, worms, trojans and other harmful computer programs hackers use to wreak destruction and gain access to sensitive information.
