Why is /home.php#… added to the address?

When you visit the site in opera, /home.php#/home.php#/home.php#is added to the address.

There is a site http://yametal.net, when I go to it in opera 11, it adds /home.php#/home.php#/home.php#etc. What could be causing this?


Answer 1, authority 100%

Maybe a virus that adds text to the address bar has met with a virus that adds strings and similar code to every page I visit
