Malware, or Malicious Software, is a computer term referring to any type of software that’s malicious in nature. In other words, malware is a very broad term that encompasses everything designed to annoy or do harm to you or your computer systems. Some examples of malware include computer viruses, worms, spyware, adware, scareware, ransomware, Trojan horses, keyloggers, rootkits, etc.

    As malware is defined by malicious intent rather than destruction or severely crippling a computer system, even applications that don’t cause computer issues but are designed to simply spy on your web browsing habits may be considered malware.
