Some approch to your problem:
-Create new automatic response
-Event group: Epo notification
-Event type: threat
Here you would likely take something like:
Thread Category = Malware or something or
Threat type = Trojan or something or
Thread Hanled = True
what ever you think should trigger the event
For Aggregation you could choose:
On Actions you just configure your mail sending cotaining the details you would like to know and an "Run system command" -> Run client task-> On demand scan for VSE you have to create bevor in ePO.
This should to the trick for you.
