Summary 📝

Malware, short for "malicious software", is a type of program designed to harm or disrupt a computer system. It can be used to steal data, damage files, or take control of a computer without the user’s permission. There are different types of malware, such as viruses, worms, trojans, spyware, ransomware and adware. Each one works in a slightly different way, but all are dangerous if not dealt with properly. Malware often spreads through downloads, emails or infected websites. To protect against malware, users should install antivirus software, avoid opening unknown attachments, and keep their devices updated. Understanding malware is important because it helps people stay safe online and protect their personal data from being stolen or damaged.
