.SYNOPSIS
    Detection script for a MEM Proactive Remediation.
.DESCRIPTION
    The Proactive Remediation will be set to check every 7 days.
    The remediation will output to a log file. So this detection on the 
    7th day will get the date of 5 days ago and if the log was modified
    at an earlier date will return non-compliant. That way this PR
    will always run weekly on machines.
