Everything is set correctly, visibility is on, it is set to private network, printer sharing is on, and still my notebook is not visible on my desktop, until i shut down the avast, when i kill avast my notebook appear on my network. I have 3 shields, in avast to kill one by one, but when i go to systray right klick and disable avast for 10 min, he says that he have 5 shields disabled. So i don't know which shield is blocking. And it is free edition of avast.
