some ppl use IsDebuggerPresent flag to switch to another routine to prevent something bla bla.. =)
but now, some technic that some thread behind will monitor for timing. Anything not right, it will kill the thread.
looking forward to have solution to over come this. anyone try this before? write C***ksMe and try it yourself.

yep, most (probably all) debuggers are single-threaded so there's definately plenty of anti-debug party tricks you can play with in other threads

if this thread just checks for timing... why not simply kill it?

or freeze it
