Firewall keeps changing settings for sharing printers etc

Recently my security system, eg. firewall, keeps changing the printer and file shaing settings. It has become very annoying, as it happens every few minutes. A large box comes up telling me the file and printer settings have been disabled, then another box follows this saying the setings have been changed what they should be, because this is a known network?
I have checked and reset all the settings to what they should be, but it still keeps happening. All my wireless connections are good to excellent, so why does this keep happening? I have been through everything and checked and diagnosed the network connections etc.
I am at a loss to what I can now do to solve this problem. Except uninstalling all my AVG and buy in a new security system!
Kind Regards Norman.
