Lesson Content/Board Summary

COMPUTER ETHICS II

Abuse/Misuse of Computers

Computer abuse or misuse refers to using a computer system in a way that is harmful, illegal, or unethical. This can involve actions that violate laws, infringe on others’ rights, or compromise the integrity and security of computer systems.

The following are examples of computer abuse/misuse:

Hacking: Gaining unauthorized access to computer systems or networks.
Cyberbullying: Using electronic communication to bully a person, typically by sending messages of an intimidating or threatening nature.
Plagiarism: Presenting someone else’s work or ideas as your own without proper attribution.
Spreading Misinformation: Distributing false or inaccurate information through computer networks.
Illegal Downloading: Downloading copyrighted material without permission.
Unauthorized Data Access: Accessing or modifying data without the owner’s consent.
Installing Harmful Software: Deliberately installing programs that can damage a computer system.

Invasion of Privacy: Computer Virus

Invasion of Privacy: This occurs when someone gains unauthorized access to an individual’s personal information, data, or online activities without their consent. This can lead to identity theft, financial fraud, or other forms of harm.

Computer Virus: A computer virus is a type of malicious software (malware) that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be “infected” with a computer virus.

Sources of Computer Viruses

Computer viruses can originate from various sources, including:

Infected USB flash drives, external hard drives, or other removable media.
Downloading pirated software or files from untrusted websites.
Opening suspicious email attachments or clicking on malicious links in emails.
Visiting compromised or unsafe websites.
Unsecured network connections or public Wi-Fi.
Malicious advertisements (malvertising) on legitimate websites.

Signs of Computer Virus Infection

A computer infected with a virus may exhibit several signs, such as:

The computer running unusually slow or freezing frequently.
Unexpected pop-up advertisements appearing regularly.
Programs crashing or not responding.
Files disappearing or being corrupted.
Unusual error messages or warning signs appearing on the screen.
Internet connection issues or unusual network activity.
Changes to your browser homepage or search engine without your consent.

Prevention of Computer Virus Infection

To protect computers from viruses, it is important to take preventive measures:

Install and regularly update reputable antivirus software.
Be cautious when opening email attachments or clicking on links, especially from unknown senders.
Scan all external storage devices (like USB drives) before opening their contents.
Download software and files only from trusted and official sources.
Regularly update your operating system and other software to patch security vulnerabilities.
Use strong, unique passwords for all online accounts.
Avoid connecting to unsecured public Wi-Fi networks for sensitive transactions.

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
