Malware is any type of software created to harm or exploit another piece of software or hardware. Short for “malicious software,” malware is a collective term used to describe viruses, ransomware, spyware, Trojans, and any other type of code or software built with malicious intent.
It’s this malicious intent that characterizes the malware definition — the meaning of malware is the damage it can inflict on a computer, computer system, server, or network. It’s the how and the why that separate one type of malware from the next. Is malware a virus?All viruses are malware, but not all types of malware are viruses. Viruses are a type of malware that self-replicate by inserting their code into other files or programs, then spreading from one infected device to another. To know whether an infection is caused by another type of malware or a virus, you need to look at how it works. If it isn’t using other programs to copy itself and spread, then it’s not a virus. What can malware do, and how dangerous is it?Malware attacks can crack weak passwords, bore deep into systems, spread through networks, and disrupt the daily operations of an organization or business. Other types of malware can lock up important files, spam you with ads, slow down your computer, or redirect you to malicious websites. Malicious software is at the root of most cyberattacks, including the large-scale data breaches that lead to widespread identity theft and fraud. Malware is also behind the ransomware attacks that result in millions of dollars in damages. Hackers aim malware attacks against individuals, companies, and even governments. What are the signs of a malware infection?The world of malware is diverse, but many types of malware share similar warning signs. Monitor your device for the following symptoms of a malware infection:
