Hostblock

This little application helps you blocking either ads or just unwanted host addresses. Instead of doing own traffic monitoring, it relies on Windows` HOSTS file to provide system-wide application-independant address blocking. Another beauty of this method is the FACT that the block list still applies and can be edited without the application.

With Hostblock, you can add new or remove old entries. Also, you can ex- and import your list to make a backup copy or pass it on.
