NIS and problems logging out of Hotmail?

Get the same message recently whenever I try and log out of Hotmail (see below).  Been happening for a month now.  Tried it in latest versions of Firefox, IE, Chrome, Opera.  Tried it on our two Win 7 PCs and my Win XP laptop.  Always the same.  The only similarity is they all have NIS 2012 installed.  Tried it at a pal's house on Win 7 & IE, but NOT NIS (he uses another internet security product), and the problem DOES NOT occur.  Tried Microsoft support which got me nowhere - they suggested deleting all cookies - made no difference.  I've not changed anything on my ADSL modem/router/Firewall for months, can't think what else it could be.

 

Could this be a NIS problem?  Anybody else seeing this problem?  Anybody any thoughts?

Regards

John
