Which of the following would MOST likely prevent malware sent as a compromised file via email from infecting a person's computer?

Patching refers to the process of updating or fixing software vulnerabilities, which can help prevent malware from infecting a computer. A firewall can also provide protection, but it primarily blocks unauthorized network traffic, not necessarily preventing infections from compromised files. Antivirus software can help detect and remove malware, but it may not prevent the initial infection. A VPN encrypts internet traffic, but it does not directly protect against malware. Thus, patching is the most likely option to prevent malware sent as a compromised file via email from infecting a person's computer.
