Domain Blocker v1.0

Domain Blocker is a Windows application that can block domains using wildcard
by filtering DNS queries. Some of its features include options to block most abused TLDs, adult/porn domains, dynamic DNS domains, free website hosting domains and
social networks. We included also a Lockdown Mode to allow only domains present in the AllowList.db file. Please note that this program will not work if you use a
secure DNS (DoH) and Encrypted Client Hello (ECH).

For Windows 7 SP1, 8, 8.1, 10, 11 (32/64-bit)

Block Domains using Wildcard

If you need a simple program to block domains using wildcard such as *.domain.com
then this program may be for you! It has a simple GUI to configure everything, it monitors any process (except Metro UI processes and session 0 processes) and you can choose
to exclude processes or monitor only specific processes like *\chrome.exe. If you use this program you should not use Secure DNS (DoH), you should use unencrypted DNS servers
such as or the one assigned by your ISP.

No System Changes
