Could be a Friday 13th thing but tried to run Skydemon 3.2 and update to 3.2.1 today and Avast Antivius 2015.10 immediately quarantined the suite of programmes. I see you have changed the update process, so no uninstalling first, but I had to revert to the old method and disable Avast to restore things to normal.

We've alerted Avast who have confirmed the defect (false positive) will be fixed in their next update.
