A user reports that their smartphone is experiencing sluggish performance and an increase in pop-up ads, especially after downloading a new game from a third-party application store. Which of the following actions should the technician take FIRST to best resolve the user's issue?
Update the device operating system
Install another antivirus application from the same third-party store
The correct action is to uninstall the recently installed game, as it is likely the source of the issue. Since the game was downloaded from a third-party store rather than the official application store, there is a higher risk of it being a bootleg or malicious application. Such applications can cause unwanted ads, degrade performance, and potentially compromise the user's personal data. While performing a factory reset or updating the OS might also resolve issues, they are more time-consuming and might not directly address the root problem caused by the third-party application. It is best practice to address the most likely cause first before proceeding to more drastic measures.
