I got to wondering the same thing about 6 months ago when I had my browser hijacked.
The URL said "all-search.com" (or something like that), but I did some netstat and tracert investigation and it turned out it was "global-finder.com".
The way it was done to me was the first part of the url was "global-finder", followed by (i think) a null + %20 + the fake URL.
So what shows up in the address bar is the fake part.
The whole URL string was obfuscated ("%blah%blah%blah....<null>%20%blah%blah%blah>") -- so it wasn't obvious to most people that "all-search.com" had nothing at all to do with the hijacking.
Just like how Wells Fargo has nothing to do with this.
The moral of the story: Never trust a link-- and never trust the words that appear in your address bar.
On the otherhand... it's pretty fun to spoof friends with that trick. I wrote a url obfuscator and then sent a link to a friend. By looking at the link, they saw "www.google.com;%20%blah%blah%blah" -- so they clicked on it -- but it actually sent them to my gag-site.
Oh, fun with technology.
