If you are having trouble running live update and going to anti-virus scanner websites then you could have a virus that blocks certain antivirus sites and disables liveupdate. Had this happen to me on a few of my computers, the virus I had was agobot (spelling might be off), and my computer was acting just like you discribed. But there are tons of viruses that can do that. If you can get on trendmirco or bitdefender try running a virus scan there to see if there is a virus getting in the way with your NAV. If in fact it is a virus messing with your updates and loading anti-virus sites you may run into difficulty getting on the scanners .... seeing those msgs like "page cannot load" etc.
On the subject of NAV, it's a great anti-virus scanner, but ya you really need to keep up on getting the definations. The problems your having doesn't sound like they are because of NAV.
