what firewall do you have?
do you have other security programs installed?
what antivirus did you use before installing avast?
did you uninstall it before installing avast?
did you use the vendors removal tool?

It could be that some setting in avast (deepscreen, hardened mode) is preventing a driver (wifi or printer) to be used.
It would help if you post a screenshot of some Avast alert when you try to print or try to connect to another computer.

And do turn your Windows firewall back on :)

Because my computer is old, I disabled deepscreen & hardened mode, this components made my pc is slowly.
Avast don't have any popup alert. When install Avast, all LAN network is disable,I can't connect any pc or printer. When I disable Avast, all is ok.
