A customer installed a new web browser from an unsolicited USB drive that the customer received in the mail. The browser is not working as expected, and internet searches are redirected to another site. Which of the following should the user do next after uninstalling the browser?
Correct Answer:
D
The customer’s web browser is likely infected by a browser hijacker, which is
a type of malware that changes the browser’s settings and redirects the user to malicious websites. A browser hijacker can also steal the user’s personal data, display unwanted ads, and install more malware on the device. To remove a browser hijacker, the user should first uninstall the browser from the Control Panel, then scan the device with an antivirus or anti-malware program, and finally install a trusted browser from a legitimate source. Deleting the browser cookies and history, resetting the browser settings, or changing the browser default search engine may not be enough to get rid of the browser hijacker, as it may have embedded itself into the system or other browser components.
A user installed a new computer game. Upon starting the game, the user notices the frame rates are low. Which of the following should the user upgrade to resolve the issue?
Correct Answer:
B
A graphics card, also known as a video card or a GPU (graphics processing unit), is a component that can affect the performance of a computer game. A graphics card is responsible for rendering and displaying graphics on the screen, such as images, animations, and effects. A computer game may require a high level of graphics processing power to run smoothly and achieve high frame rates, which are the number of frames per second (FPS) that the game can display. Upgrading to a better graphics card can improve the performance of a computer game by increasing its graphics quality and frame rates. Hard drive, random-access memory, and monitor are not components that can directlyimprove the performance of a computer game.
A technician is working on a Windows 10 PC that has unwanted applications starting on boot. Which of the following tools should the technician use to disable applications on startup?
Solution:
Task Manager is the best tool to use to disable applications on startup in Windows 10. Task Manager is a built-in utility that shows the current processes, performance, and users on a system. It also has a Startup tab that lists the applications that run on boot and their impact on the system. The technician can use Task Manager to disable or enable any application on startup by right-clicking on it and selecting the appropriate option. System Configuration, Performance Monitor, and Group Policy Editor are other tools that can be used to manage system settings, but they are not as simple or convenient as Task Manager for this task.
