CompTIA A+ 220-1102 Practice Question

The correct answer is 'A malware infection'. Malware often modifies, deletes, or renames files and folders to disrupt operations or hide its presence. This is a common symptom of malware that has been designed to manipulate user data. The incorrect answers do not typically result in files being missing or renamed: 'A disk defragmentation' simply reorganizes the data to improve efficiency; it does not delete files. 'User account corruption' can result in an inability to access files or settings but would not typically rename folders. 'An automatic OS update' may sometimes cause settings or configurations to revert or update, but it does not rename or remove user documents.
