DialGuard

DialGuard is the only program in the world which can prevent your phone bill
from running wild as a result of small sneaky Dialer programs.

DialGuard blocks calls to all phone numbers which have not been approved by
you first, and in that way it prevents the Dialer programs from operating as
intended. With DialGuard you can be sure that your PC never makes calls
abroad or to any sex sites.

If a program tries to call a phone number which has not been approved by you
first the call is blocked and you receive an alarm message on screen.

DialGuard has patent pending status in Europe and the USA.
