CompTIA A+ 220-1102 Practice Question

Scanning the system with updated antivirus software is the correct initial step in this scenario. It allows for the detection and mitigation of any malware which might be responsible for renaming files or disrupting application functionality. Updating the antivirus ensures the latest threats can be recognized. Alternatively, contacting IT support or checking recent system updates might not directly address the possible presence of malware, which is suggested by the symptoms described. System Restore could revert important updates or changes and should only be used when other steps to address potential malware have been exhausted.
