Malware is short for malicious software. Malware can be considered a classification of different malicious software pieces, such as viruses, worms, spyware, Trojan, ransomware, crypto-mining, or other software types that you do not want on your computer. Malware can get on your computer from several different means, including email attachments, harmful websites, unknown USB drives, or other ways of attack. To protect against malware, you'll want some sort of antivirus and firewall on your computer, which can stop most, but not all, malware.
