Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack. 

A computer virus is a type of malicious software (malware) designed to spread from one computer to another and interfere with normal computer operation. It typically attaches itself to legitimate files or programs, and when those are run, the virus becomes active—replicating itself and potentially causing harm.

Key Characteristics of a Computer Virus:

  • Self-replication: A virus can make copies of itself and spread to other programs or systems.

  • Activation by user action: Most viruses require some action from the user to activate (like opening an infected file).

  • Payload: Once activated, a virus might:

    • Corrupt or delete data

    • Slow down system performance

    • Steal sensitive information

    • Display unwanted messages

    • Allow hackers remote access

Common Ways Viruses Spread:

  • Email attachments

  • Infected software downloads

  • Removable media (like USB drives)

  • Vulnerabilities in outdated software

Protection Tips:

  • Install and update antivirus software

  • Avoid opening suspicious email attachments or links

  • Keep operating systems and software up to date

  • Use firewalls and strong passwords

Let me know if you'd like examples or the difference between viruses and other malware types like worms or trojans.
