OK thanks, I just did that.  Some tips.  I spent the entire day, first with a "Norton tech" who wanted to charge me $140 to fix Poser.   When I asked who he really was, he gave me the Norton support link and disappeared.  A few weeks ago, I couldn't get into Yahoo.  A "Yahoo tech" wanted to charge me $300 or (or "how much can you pay?").  When I questioned him, he disappeared.  The rest of today, I spent with a real Norton tech who removed the firewall, proving that it is most likely my own computer problem.  

I tried updating IE from 6 to higher, and had problems downloading it (couldn't).   

My lesson for today is be careful when you click on support sites.   Lot of wolves there.
