Cant connect online

I wonder can someone please help me, last night i downloaded and installed norton online family cause i have heard alot of good stuff about it but after installing it i could not connect to the internet even kids sites everything was blocked i checked the settings on my daughters profile and everything seems fine i uninstalled it and everything was fine so i installed it once more and the same happend.

I am using avast anti virus and i also am using juniorwatch could this be clashing with norton and dissconnecting me from the internet.
