A U.S. district court has shut down an operation that secretly
downloaded multiple malevolent software programs, including spyware,
onto millions of computers without consumers’ consent, degrading their
computers’ performance, spying on them, and exposing them to a barrage
of disruptive advertisements. The Federal Trade Commission has asked
the court to order a permanent halt to these deceptive and unfair
downloads, and to order the outfit to give up its ill-gotten gains.
