DNStest
Test Description
DNStest attempts to launch and then infect svchost.exe.
Svchost.exe is usually a trusted application that can connect to the Internet because the default Windows DNS client service resides in svchost.exe.

You will see the dialog box shown above if your firewall fails this test. To pass, your firewall should block the DNS query and ideally alert you to the connection attempt.
