I heartily endorse the conditional reports. If virus engine/definition is not current send me a report otherwise don’t fill up my email with a blank report. If no machines were infected within the last 24 hours don’t fill up my email with blank reports. Maybe a status report that you can check the critical things you want and if none meet the criteria send 1 all fine message or option to send nothing at all. Opening blank PDFs just wastes time. I’d rather see a subject line saying Avast is updated in my enterprise and nothing is infected. I can then just move on to the next email without even opening the avast message. Or if something is wrong state it in the subject line and then I know to open the PDF.
