What are Computer Viruses? Who writes them?

A computer virus is a malicious program or file that replicates itself by copying itself onto other computers or devices.

It is typically designed to damage or disrupt a system, or to gain access to confidential data.

Computer viruses are usually written by hackers, cybercriminals, or script kiddies with malicious intent.

Examples include Worms, Trojans, Ransomware, Spyware, Adware and Backdoors.

Worms are self-replicating malicious programs that spread across networks and systems, often through email attachments.

Trojans are malicious programs that disguise themselves as legitimate software, but once executed, can cause significant damage to an infected system.

Ransomware encrypts files on the infected system, making them inaccessible until a ransom is paid.
