I haven't changed a single thing on my computer for months - no reason it should just suddenly 'not work'. My firewall etc are the same as they have always been.

Sometimes I cannot access PC from IE but can from Mozilla, so I just tried Yahoo from Mozilla - same thing!!!

and very frustrated.

I appreciate all the support though.

PS - I actually have changed something on my computer. I took off Norton and now use AVG - but I had not problems with Yahoo until about 3 days ago ....
