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 X-rated 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.
