The best explanation for why the system still has malware after performing a System Restore is that the malware was installed before the system restore point was created. A system restore point is a snapshot of the system settings and configuration at a certain point in time. A System Restore is a feature that allows users to restore their system to a previous state in case of problems or errors. However, a System Restore does not affect personal files or folders, and it may not remove malware that was already present on the system before the restore point was created. A system patch disabling the antivirus protection and host firewall may increase the risk of malware infection, but it does not explain why the malware persists after a System Restore. The system updates not including the latest anti-malware definitions may reduce the effectiveness of malware detection and removal, but it does not explain why the malware persists after a System Restore. The system restore process being compromised by the malware may prevent a successful System Restore, but it does not explain why the malware persists after a System Restore.

The first step a technician should take when troubleshooting a computer with a suspected short in the power supply is B. Disconnect the power before servicing the PC. This is to prevent any electrical shock or damage to the components. A power supply can be dangerous even when unplugged, as capacitors can maintain a line voltage charge for a long time. Therefore, it is important to disconnect the power cord and press the power button to discharge any residual power before opening the case. The other steps are also important for safety and proper diagnosis, but they should be done after disconnecting the power.

Correct Answer: A

The most likely cause of the user's laptop issues is that it has been infected by some type of malware or ransomware. Malware and ransomware are malicious software that can harm, exploit, or disrupt devices or networks12. They can cause symptoms such as slow performance, browser redirects, pop-up windows, data encryption, or ransom demands12. Therefore, the first step a technician should take to resolve the issue is to scan the laptop for malware and ransomware using a reliable and updated anti- malware tool34. This can help identify and remove any malicious software that may be present on the laptop. Scanning for malware and ransomware is more effective and urgent than the other options because: Performing a system restore may not remove the malware or ransomware, as some of them can persist or hide in the system files or backup copies34. Moreover, a system restore may result in data loss or corruption, as it restores the system to a previous state and deletes any changes made after that point5. Checking the network utilization may not help diagnose or fix the problem, as the malware or ransomware may not be using the network at all, or may be using it in a stealthy or encrypted manner34. Furthermore, checking the network utilization does not address the root cause of the issue, which is the presence of malicious software on the laptop. Updating the antivirus software may not be sufficient to detect or remove the malware or ransomware, as some of them may evade or disable the antivirus software, or may be too new or unknown for the antivirus software to recognize34. Additionally, updating the antivirus software does not guarantee that the laptop will be scanned for malware or ransomware, as the user may need to initiate or schedule the scan manually.

Correct Answer: D

The best solution for a technician to implement is to disable the browser from sending notifications to the Action Center. This will prevent the random advertisement notifications from appearing in the Windows 10 Action Center, which can be

annoying and distracting for the user. The technician can follow these steps to disable the browser notifications1:

Open the browser that is sending the notifications, such as Microsoft Edge, Google Chrome, or Mozilla Firefox.

Go to the browser settings or options menu, and look for the privacy and security section. Find the option to manage site permissions or notifications, and click on it. You will see a list of sites that are allowed or blocked from sending

notifications to the browser and the Action Center. You can either block all sites from sending notifications, or select specific sites that you want to block or allow.

Save the changes and close the browser settings.

This solution is better than the other options because:

Running a full antivirus scan on the computer (B) is not necessary, as the advertisement notifications are not malicious or harmful, and they are not caused by a virus or malware infection. Running a scan will not stop the notifications from

appearing, and it will consume system resources and time. Disabling all Action Center notifications ?is not advisable, as the Action Center is a useful feature that shows notifications and alerts from various apps and system events, such as

email, calendar, security, updates, etc. Disabling all notifications will make the user miss important information and reminders, and reduce the functionality of the Action Center. Moving specific site notifications from Allowed to Block (D) is not

the best solution, as it will only stop the notifications from some sites, but not from others. The user may still receive advertisement notifications from other sites that are not blocked, or from new sites that are added to the Allowed list. This

solution will also require the user to manually manage the list of sites, which can be tedious and time- consuming.
