I cannot udate my software or use IE. I receive an unable to find server message when I try, but with Firefox there are no problems when I access the Internet, and I can go anywhere. This started about 1 week ago. Nothing notable happened. My updates are automatic, and I am very careful about the sites I go to. Suddenly I could not update anything. Then I found only Firefox could access the Internet. I reset everything I could. I reloaded IE and even tried to download another IE version.No luck and it is very frustrating. Help please.
