9. Activity 1: “Visual diagnosis” Watch and pay close attention to the video. Analyze and write down the effect/s of a virus on both human bodies and computer software .

10. Learning Objective 6: Recognize malwares to ensure security of data . Maintain computer equipment and systems.

11. MALWARE Malicious Software Refers to any intrusive software developed by cybercriminals to steal data and damage or destroy computers and computer systems.

12. TYPES OF MALWARE

13. VIRUS A type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. If this replication succeeds, the affected areas are then said to be “infected” with computer virus.

14. WORM Exploits vulnerabilities in your security software to steal sensitive information, install backdoors that can be used to access the system, corrupt files, and do other kinds of harm.

15. TROJAN HORSE A type of malware that downloads onto a computer disguised as a legitimate program.

16. ADWARE A type of malware that displays unwanted advertisements on your device, often in the form of pop-ups or banners.

17. SPYWARE A malicious software that enters a user’s computer, gathers data from the device and user, and sends it to third parties without their consent. An unwanted software that spied on their user and computer activity.

18. RANSOMWARE A type of malware which prevents you from accessing your device and the data stored on it, usually by encrypting your files.

19. SAMPLE ENCRYPTED DOCUMENT SAMPLE ENCRYPTED FILES/FOLDERS

20. KEYLOGGERS A keylogger or keystroke logger/keyboard capturing is a form of malware or hardware that keeps track and records your keystrokes as you type.

21. ROOTKITS A type of malware designed to give hackers access to and control over a target device.

22. PHISHING A type of social engineering attack often used to steal user data, including login credentials and credit card numbers.

23. Activity 2: Brainstorm and list down different strategies in preventing malware attacks.

24. Strategies to prevent malware attacks: Use anti-virus software Use strong password Keep software up-to-date Be cautious with downloads Back up data

25. Activity 3: Recognize malwares based on their specific characteristics described in each scenario.

26. Case 1 A user, "David", notices that his computer is running slowly, and strange processes are running in the background. An investigation reveals that his computer is infected with malware that has hidden itself deep in the system and is allowing hackers to access the computer remotely.

27. Case 2 A business owner, "Mike", discovers that someone has been accessing his computer remotely and stealing sensitive business data. An investigation reveals that his employee's computer was infected with malware that captured every keystroke made on the keyboard.

28. CASE 3: A small business, "Green Cleaners", has been infected with a malware. The malware, known as " Cryptolocker ", has encrypted all of the company's files and is demanding a ransom payment in exchange for the decryption key. The business owner is unsure of what to do and is worried about losing important data and business operations.

29. CASE 4 A college student, "Emily", receives an email from what appears to be her bank's email address. The email claims that her account has been compromised and asks her to click on a link to reset her password. However, the email is actually a n attempt by hackers to steal Emily's login credentials.

30. CASE 5 A user, "Sarah", installs a free software download from the internet. Unbeknownst to Sarah, the software is infected with malware that generates pop-up ads and tracks her online activity. The malware also slows down Sarah's computer and makes it difficult to browse the internet.

31. ASSESSMENT: keystroke logger/keyboard capturing is a form of malware or hardware that keeps track and records your keystrokes as you type. A type of malware that downloads onto a computer disguised as a legitimate program. A malware designed to deliver targeted advertisements or infected computers. An unwanted software that spied on their user and computer activity A malware that often used to steal user data, including login credentials and credit card numbers KEYLOGGER PHISHING ADWARE SPYWARE TROJAN HORSE

32. A malware infection can have serious consequences for computer software and data. By understanding how a virus spreads and affects computer software, you can take steps to prevent and remove an infection. Remember to always use antivirus software, keep software up-to-date, and be cautious when downloading software or opening email attachments.

33. Assignment: List down best practices to ensure safety of data in your devices.
