Starting yesterday, every time that I restart my computer,
a website called "casino palazzo" opens automatically. At
the same time, a dialog box opens wanting to install web
dialer, and a shortcut appears on the desktop with an X on
it and the word "sex". Are these trojans, and how do I get
rid of them? They are very irritating.
