Dude MSN Explorer is an advanced browser, that integrates into many Microsoft services and applications, including: MSN Hotmail, MSN Messenger Service, MSN Communities, MSN eShop and others. It has no built-in firewall or anything, you maybe experiencing software conflicts, try disabling startup or uninstalling just to see if thats the problem, but what I know is that its NOT MSN Explorer firewall, because it doesnt exist!!!!!!

Thanks. ;d
