End-user education is crucial after malware removal to prevent recurrence. Teaching safe browsing habits and security awareness completes the remediation cycle.
Mark Soper - Mike Meyers ' Lab Manualstates:
"Educating the user after malware remediation is part of the CompTIA malware response methodology. This includes training on phishing and safe practices."

The correct answer is A. Reinstalling the application, because the issue appears to be application-specific rather than system-wide. The problem only affects one game, the operating system is fully updated, and there are no storage constraints. These indicators strongly suggest corrupted application data or a faulty app installation.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, when a single application crashes repeatedly, the first recommended troubleshooting step is to remove and reinstall the app. This clears corrupted files, resets application settings, and ensures the latest compatible version is installed.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that factory resets should only be used as a last resort, as they are disruptive and erase user data. Disabling background applications may help performance issues but does not typically resolve persistent crashes tied to one specific app.
The Mike Meyers / Mark Soper Lab Manual further clarifies that date and time misconfiguration usually affects authentication or certificate validation, not game stability.
Because the symptoms are isolated to a single application and basic system factors have already been ruled out, reinstalling the application is the most appropriate first troubleshooting step, making A the correct answer.

The correct answer is A. Hashing, because hashing is specifically designed to verify file integrity and detect whether a file has been altered after its original creation or distribution. A hash is a fixed-length value generated by running a file through a hashing algorithm such as SHA-256 or SHA-1. Even a single-bit change in the file will produce a completely different hash value.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, hashing is commonly used to validate downloaded software by comparing the calculated hash of the downloaded file with the hash published by the vendor. If the two values match, the technician can be confident that the file has not been modified or tampered with.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that hashing ensures integrity, not confidentiality or authentication. SSL certificates secure data in transit, but they do not validate files after download. Plug-ins and extensions provide additional browser functionality but have no role in verifying file integrity.
The Mike Meyers / Mark Soper Lab Manual reinforces that hashing is a standard best practice in secure software deployment and malware prevention. It allows technicians to confirm that files are exactly as the publisher intended.
Because the requirement is to confirm that files have not been modified, hashing is the correct and most reliable method, making A the correct answer.

The correct answer is C. Cryptominer . Cryptominer malware secretly uses a victim computer's processing resources to mine cryptocurrency for an attacker. Because cryptocurrency mining requires heavy computation, this malware commonly causes unusually high CPU or GPU usage. The All-in-One Exam Guide explains that cryptominers take control of a computer's hardware resources to mine cryptocurrency and that a telltale sign may be inexplicably high GPU or CPU utilization. The Mike Meyers/Mark Soper material states the same concept: cryptominer malware uses the target system's CPU or GPU, and one sign of infection is unexplained high resource usage. A keylogger records keystrokes, a Trojan disguises itself as legitimate software while performing malicious actions, and a rootkit hides itself using low-level OS access. Those malware types can be dangerous, but high CPU usage most strongly points to a cryptominer.

RAM is an electrostatic-sensitive component. When removing or transporting RAM modules, they should be stored in antistatic bags to protect against electrostatic discharge (ESD), which can damage the memory. This is a standard best practice in hardware handling.
A). Demagnetization is not applicable to RAM.
C). Plugging in power to ground is not safe or recommended for static protection.
D). Installing identical memory pairs is applicable for dual-channel configuration, but not directly related to transporting or handling RAM.
