Hello, good day.. i have no internet connection so i have to update my kapersky manually..
the problem is i can't download the update database..every time i click the external mirror or the download location this one appears:


Server not found




Firefox can't find the server at dnl-pr1.kaspersky-labs.com.




* Check the address for typing errors such as
ww.example.com instead of
www.example.com

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
