This question was asked > 2 years ago, but I don't think the answer given actually answered the question:
The "action" in the answer is an immediate action - but does not define anything about setting this up as an ongoing, scheduled task. This is similar to the information here, for current product:
https://support.eset.com/en/kb7815-send-a-wake-up-call-to-client-computers-to-execute-a-task-immediately-in-eset-protect
I have the same question, can a "wake up" action be scheduled as a task, so that any computers that are sleeping can be woken in order to do a full scan during non-business hours?
