Question #8

Topic 1

A user reports seeing random, seemingly non-malicious advertisement notifications in the Windows 10 Action Center. The notifications indicate the advertisements are coming from a web browser. Which of the following is the BEST solution for a technician to implement?

• • A. Disable the browser from sending notifications to the Action Center.

• • B. Run a full antivirus scan on the computer.

• • C. Disable all Action Center notifications.

• • D. Move specific site notifications from Allowed to Block.

Answer explanation

Run a full antivirus scan on the computer would be the best solution for a technician to implement in this case. While the advertisements may not appear malicious, they could potentially be part of an adware or spyware program that is running on the computer. Running a full antivirus scan can help detect and remove any malicious software that may be causing the unwanted notifications. Disabling the browser from sending notifications, disabling all Action Center notifications, or moving specific site notifications from Allowed to Block may not address the underlying issue of a potential malware infection.

• • B. File a trouble ticket with the bank.

• • C. Contact the ISP to report the CFO's concern.
