Trojans and Worms

Trojans are malicious programs disguised as legitimate software. They do not self-replicate but can steal data, create backdoors, or damage systems. Worms, on the other hand, are self-replicating programs that spread automatically over networks, often causing widespread disruption.

Examples and threats:

• Trojans: Fake software, cracked programs, or email attachments that execute malicious code.
• Backdoor Trojans: Allow attackers to control the infected system remotely.
• Worms: Spread via networks, emails, or removable drives without user action.
• Exploit Worms: Exploit vulnerabilities to propagate automatically.

To protect against Trojans and Worms, users should avoid downloading software from untrusted sources, keep antivirus software updated, and monitor unusual network activity.
