“The class action complaint alleges that DoubleClick deceptively and
fraudulently commandeered millions of Internet users to the
commercial websites of DoubleClick’s customers through dissemination
of tens-of-millions of fraudulent Internet advertising banners that
impersonated computer error messages. The Complaint states that
through use of such Fake User Interface (“FUI”) dialogs that gave the
false appearance of being computer error messages, DoubleClick
tricked millions of Internet users into interrupting the work they
were performing to respond to the fraudulent error message, only to
unexpectedly find both computer and computer user thus hijacked to
the commercial websites of DoubleClick’s customers.”
