When I click on internet explorer,it goes to my home-page
[yahoo] and for many other action I get an error[this
page cannot be displayed-cannot find server]for any
common address,AND I get the followingin the address bar
[which seems to lock out my browser]:

Sounds like you are riddled with spyware/adware/scumware. Download and run
one or both of these: Spybot S&D http://www.safer-networking.org/
or AdAware http://www.lavasoft.de/software/adaware/ . Most will recommend
running both because it always seems one will find what the other one won't.
I think you'll be amazed at what these find on your system.
