We have a [younger] sister company in Scotland using Avast. It’s configured to run a PC scan every Wednesday night at 10PM their time.
Today [Thursday], I went in remotely to check on the results. Strange. While the Scheduler still says to run the scan at 10PM every Wednesday, the client side tasks reported a 9PM scan and a 10PM scan.
Saw the same behavior in my network (in the USA). The first time each of Avast’s scheduled tasks ran after the time change, it ran twice. The duplicate runs were an hour apart.
