1. You should be able to use the Eicar test site as that has both http and https transmission of the test file/s.
2. Since there is nothing in the Scan Settings - Scheduling - in relation of missed time, I would suspect it would only wait for the next occurrence.
- With a resident (on-access) scanner the need for on-demand scans is much depreciated. For the most part dormant/inert files are being scanned, the other active files are going to be scanned by the resident shields when they are activated.
3. Even if this were possible, it would really slow startup, running a scan whilst windows and programs are starting. The regular resident on-access scanning would be going on at that time also.
4. There are two sets of exclusions Global and Shield level exclusions, Global would cover on-demand/scheduled scans.
