Anybody know of Norton interfering with Windows Live Mail?

Hello, all,

I am trying to resolve an issue with WLM (running in W8) where I am told the server has unexpectedly terminated the connection, and another, similar message; and having, as far as I am able, ensured all the settings are correct, option 2 seems to be a possibility that my security software (mine is Norton Internet Security) is blocking something, somewhere.

Does this ring any bells with this community?  Any pointers would be helpful, but please note I am a home user, and not an IT specialist!

Thank you

Peter
