Server disconnects

Am new to posts…sorry!
Have Avast 4.8 and am noticing that daily my computer (which is the server for a company file), will say ‘server is now connected’ and it will have disconnected everyone that was connected to the company file and they will have to get out of the program and get back in. If by chance they had entered something into the company file that wasn’t saved yet, they lose it. Could Avast be knocking the server communication off for a period of time for some reason???

There isn’t a whole lot of information here, but no, that shouldn’t happen at all.

Where are you seeing this?

server is now connected

Sounds more like a loose network cable on your server/switch/whatever else it’s plugged into.
