What software is essential for detecting viruses?

• A. DriverView
• B. API Monitor
• C. PA File Sight
• D. virus scanner

Answer: (D)

Virus detection hinges on software that actively scans and flags malicious code across the system. A virus scanner (antivirus software) uses a database of virus definitions and a scanning engine to examine files, processes, and memory for known signatures or suspicious behavior. It can run on demand or in real time, alert you to threats, and quarantine or remove infected files, with updates to stay current against new malware. The other tools serve different purposes: DriverView lists device drivers, API Monitor observes API calls for debugging or malware analysis, and PA File Sight monitors file activity but isn’t designed to primarily detect and remove malware. So, the essential tool for detecting viruses is the virus scanner.
