Avast Firewall Issue with BT Home Hub 5

I have recently been plagued with connection issues to my router since the last AVAST program update and was baffled somewhat. My wifi consistently disconnects and I end up having to reboot my computer as the BT Help software is unable to restart the wifi connection. I presumed it was the Windows firewall causing the problem but even when this was disabled it continued to disconnect. As a last resort I tried to turn off the AVAST Firewall but was unable to do so through the settings. I ended up having to uninstall the AVAST Internet Security 2015 Program leaving the Windows firewall active. Lo and behold I have not had one disconnection since that time (even with the windows firewall activated). Why was this happening?

PS I am using Windows 7 Home edition and have been using AVAST for a few years without issues.

Initially turn off the HTPPS setting in webshield

I had to uninstall AVAST 2015 completely as I stated. I ran the computer for a few hours and no disconnections at all (tested with both Windows Firewall on/off). The reason for the uninstall was that the turn off the Avast Firewall would not work at all through the settings.

I decided to reinstall AVAST 2015 and as yet there have been no disconnections but also I am able to turn off/on the AVAST Firewall now!

I have had the computer running for a couple of hours and there have been no disconnections what so ever which is good news for me.

One thing I will say is that my computer is running a lot slower since the re-install so I will check my settings again.
