In which log would an event related to a failed application startup due to a malicious process be recorded on a Windows server?

An event related to a failed application startup due to a malicious process would be recorded in the Application log on a Windows server. This log is specifically designed to capture events related to the operation of various applications running on the system, including error messages, warnings, and informational messages about the applications themselves.

When an application fails to start, whether due to a legitimate error or interference from a malicious process, it triggers an entry in the Application log that helps administrators understand performance issues and application behaviors. This log is essential for troubleshooting and diagnostics, especially when dealing with potential security incidents where a malicious process might disrupt legitimate application functionality.

In contrast, while the Security log records security-related events like successful or failed logons and access attempts to resources, the System log captures system-level events, such as those involving drivers or hardware issues. The Forwarded log is used for collecting events sent from remote computers, not directly pertaining to the local application status. Thus, the Application log is the most appropriate choice for events focused on application behaviors and errors.
