Malware is short for "malicious software". It is a catch-all term for any program or file that is intentionally harmful to a computer, network, or server. Malware can infect all types of electronic devices, including cell phones, personal computers, tablets, smart televisions, and even gaming systems. Malware is developed by cybercriminals to steal data, damage, or contaminate an electronic device, or to gain unauthorized access to information or systems. Malware comes in many variants, including viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wiper, and keyloggers. The goal of malware is to cause havoc and steal information or resources for monetary gain or sheer sabotage.
