Explanation

Look out! Computer programs that are intended to cause harm or damage your computer are malware. Viruses and spyware are common types of malware. Malware is a code or file that's meant to injure computer users by stealing their data, secretly monitoring their activity, or harming the computer itself. The term malware, which was first used in 1997, is short for "malicious software." If your computer has a firewall or antivirus software, that's your protection against malware. You can also avoid it by not clicking on mysterious links sent from unknown email addresses.
