Avoid all calls on your modem, except the numbers you authorize.
Dialers have been a problem during a long time, even though with the massive implementation of router and
ADSL connections this problem has been minimized, but it is also true that there are still many connections that work via
modem due to various reasons. So to avoid that our bill rises way over the usual, it is better to use a program like
Digisoft AntiDialer.
Dialers are programs that have been created to sneak into a computer that connect to Internet via modem and
change the telephone number that the modem uses to connect to Internet. These program
change the number of the switchboard (that is usually local or reduce price) for another one with
special pricing (where they make money). But with
Digisoft AntiDialer we will protect from this kind of fraud.
Digisoft AntiDialer works with a
clean number list to which it allows to call. So if any
dialer changes the configured number for another one that isn't on any list, it is automatically blocked.
Usually antivirus applications have some kind of similar protection to that offered by
Digisoft AntiDialer, but it is always better to have an
application that is specifically designed against this kind of threat, because you never know from where they come or if the antivirus detects it correctly.
