What is Malware and Why Should You Care?

Malware—short for malicious software—refers to harmful programs like viruses, worms, ransomware, spyware, and trojans designed to damage, steal, or take control of your devices.

Common Malware Types Include:

Viruses: Spread by attaching to files and programs.
Ransomware: Encrypts your files and demands payment.
Spyware: Secretly monitors your activity.
Trojans: Disguise themselves as legitimate software.
Worms: Spread independently across networks.

According to Norton Security, malware infections can result in identity theft, financial loss, and permanent data damage. That’s why swift, thorough removal is critical.

If you notice any of these, it’s time to take action.
