Malware, short for malicious software, is designed to damage or exploit computers and networks.

Common types of malware include viruses, worms, trojans, ransomware, spyware, adware, and rootkits.

Viruses attach to legitimate files and spread, corrupting or deleting data.

Worms spread independently, exploiting software vulnerabilities to infect networks.

Trojans disguise themselves as legitimate software to create backdoors for other malware.

Ransomware encrypts data and demands a ransom for decryption.

Spyware secretly monitors user activity to steal sensitive information.

Adware displays intrusive ads that can degrade system performance.

Malware infiltrates systems through phishing, drive-by downloads, software vulnerabilities, and social engineering.

Protect against malware by using antivirus software, keeping systems updated, educating users, backing up data, enabling firewalls, using multi-factor authentication, and monitoring network traffic.
