Understanding Malware and Its Types

Malware is short for “malicious software.” It includes harmful programs designed to damage or misuse computer systems. The definition of malware covers a wide range of threats that affect computer security. Knowing about malware helps users protect their systems from its dangers.

What is Malware?

Malware refers to various harmful programs like viruses, worms, Trojan horses, spyware, and ransomware. Each type acts differently. For example, a virus spreads by attaching to legit software.

• Worms: These spread by themselves across networks, causing lots of damage.
• Trojans: Disguised as safe software, they trick users, allowing data theft.
• Spyware: It secretly watches user actions and steals personal info without permission.
• Ransomware: This software locks files and asks for money to unlock them, becoming increasingly common.
• Adware: It shows ads and can annoy users, sometimes looking harmless.

Understanding these differences helps users spot threats early. It’s essential to keep up with malware changes to protect personal details and keep computers running smoothly.
