Malware definition
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. As Microsoft puts it, “[malware] 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.
