Thank you for your interest and reply To answer your queries 2 and 3 I will have to take some time to review in depth to give relevant replies - I may not be able to do that of a few days when I will get back with replies. I also want to check and make sure I did not miss anything in the program. Re KTS version & patch(x) = 21.2.16.590(b) Re Q4 - from your reply it seems that Trusted Applications mode, is a different module/ functionality to Trusted Applications not the same as I assumed - could you explain the difference or give me a reference to explain this, though, the first is perhaps moot as it is unavailable, and for the second I should find the answer in the Threats and Exclusions help page. I will try to complete the other items as soon as I can, Best regards
