Ya know, ever since Yahoo "suggested" I agree to their free upgrade I've had nothing but trouble with it myself.

Your better off just re-starting your computer and go back to your Yahoo account and try again.

Yahoo recently changed their e-mail site and "shut down" the old one...they should have auto-converted your stuff over to the new site.  go to yahoo.com and try to click on email..one works and one say's it no longer works (i forget how to tell them apart).  I hope that helps!!!!

So many people have had problems with Yahoo mail over the past year that it might be wise to switch to something different. Having said that, I still use Yahoo, but my main email  client is hotmail, but if I start having the problems I've heard about, I'll change (probably to gmail). I doubt your problem is caused by a virus.
