I've been using Avast IS for some time now, and I've been using native Windows function - hosted network, to share connection across my other devices via WiFi (I have only one modem, plugged in to usb port). Recently (can't exactly say when) Avast firewall started to block connection. I can still connect to network using other devices, but as long as firewall is turned on on my main pc, there is 'no internet connection' on others. When I disable firewall, everything works great. I HAVE intenet sharing mode turned on, I have latest (12.3.2280) version, I've restored default settings of whole Avast IS. What can I do to make it work?
