On an XP Pro system, I am using: NOD32 v4.0.437.0 Online Armor 126.96.36.199 Spysweeper 188.8.131.52 (not with A-V) Thunderbird 184.108.40.206 with Cloudmark Desktop 1.0 (spam blocker) A. In the Threat Sense Engine default "options" in Thunderbird's setup, everything is checked except "potentially unsafe applications". That seems more of a threat than "potentially unwanted applications" (which is checked.) Why is the default set up that way? Isn't unsafe worse than unwanted? B. Are there other "consensus best settings" to adjust? C. Cloudmark identifies spam upon arrival, moves it from the inbox to the junk folder. Every time it is moving an email from the inbox to the junk folder, I get this message: "An error occurred communicating with the Cloudmark Service". I also have this in the Scanner Setup (not sure which of these I should check): http://screencast.com/t/aVEgGKTFbxLR What do I need to do to allow Cloudmark to work right?
