Armadillo CC, I can't understand the meaning
who can tell me,thanks

This means authors of this packer go there for hollidays

0xCC is the bytecode correspoding to an INT3 breakpoint. When a thread encounters such an instruction it throws an EXCEPTION_BREAKPOINT exception. These shouldn't exist when no debuger is present (or the unhandled exception filter will kill the process).

The only thing INT3s have to do with Armadillo is the Nanomites protection, which is a subset of Debug-Blocker.

Search 'Nanomites' (Ricardo and Crusader have produced the most complete tutorials on the topic) and come back when you have a specific problem.
