Hello, I asked a similar question previously, so apologies that I can't find it.

1  My Sophos Home Says "last Updated" when the relevant pc was last switched on - even though it was not attached to the internet (no wireless, ethernet unplugged). The time of update doesn't match any time on the sophos website (image c)

2  After I run a scan the software says a scan has been completed (image aa)

3 When I reboot (again, without connecting to the internet) the software says that a scan has never been run (image b)

Please will someone explain why the software is reporting this?
