    hi
    Simplefirewall can detect them whithout disabling dns cache
    do you mean that disabling dns cache service even SpyShelter can catch services ( look #22)?
    thanks

    By default DNS Cache makes DNS requests using svchost.exe, if it is disabled, all DNS requests (via port 53) are made by apps themselves, requiring DNS rules in the firewall for each.

    Always, since Vista. DNS Cache makes no sense with fast DNS servers like 1.1.1.1, not to mention, that it helps to mitigate some attacks, like DNS poisoning, etc.
