• ITIL (B): A framework of best practices for IT service management.
• Linux (C): An open-source operating system.
• Antivirus (D): A utility program designed to protect a computer system. It continuously monitors the system, scans files for matching virus signatures, detects unusual program behaviors, and safely quarantines or deletes detected threats to prevent system infection.

Step 3: Conclusion:
The utility software used to prevent, detect, and delete computer viruses is an Antivirus program, matching option (D).
