Which statement describes the purpose of antivirus software?

• A. Searches for, detects, quarantines, and removes viruses
• B. Encrypts files to prevent access
• C. Scans for printer errors
• D. Monitors screen brightness

Answer: (A)

Antivirus software is designed to protect a computer from malware by actively looking for threats and taking action to stop them. It searches files and programs for suspicious patterns, detects known viruses (often using a database of virus signatures) and unknown threats through behavior analysis, then quarantines suspicious items to isolate them and removes or repairs infected files. It can also provide real-time protection, monitoring activity to catch threats as they try to run. This combination of searching, detecting, quarantining, and removing is what keeps systems safe from viruses. The other options describe tasks that aren’t about stopping malware: encrypting files to prevent access is about data protection, scanning for printer errors deals with hardware or driver issues, and monitoring screen brightness is a display setting.
