Para quem a mensagem informa sobre a porta 53:
I believe the issue is that there is an application on your system that is either receiving data to your local port 53, or is sending data to another remote host on its port 53 which is not DNS related.
Outpost is (correctly) informing you that there is non-DNS related information being transferred on the well known DNS port. This is useful as it can catch out malicious programs that may be trying to bypass a firewall by masquerading its data as a legitimate DNS request so that it may be passed by any "DNS Allow" rules in the rulebase - but Outpost is smarter than this, as it checks the content of the data to see if it really is a DNS request or not - if its not, then you are warned via the "malformed" popup.
Em ultimo caso:
Given problems currently existing with the DNS cache plugin -- best suggestion is to "Stop" the DNS Cache plugin until problems with it are solved in new releases -- i.e. problem more likely related to problems with the plugin than actual problems.
Tenho usado a OP e nao tenho razao de queixa.
Desactivei o plugin anti-spyware. So consome recursos e alem disso uso Anti-virus / ad-aware / M$ anti-spyware para isso.
