Hello,
version 4 of CIS didn't improve anything regarding passing leaktests on Windows Vista or Seven x64.
Still it doesn't block the Matousec SSTS tests regarding:
-keylogging
-DLL injections (global hooks)
-window messages
-OLE automation
-DDE
It fails these tests (incomplete list but should include ~all techniques):
kill3f (example for window messages)
keylog1 (keylogging)
breakout1
cpilsuite2 (Outpost warns about global hook)
ddetest
flank
osfwbypass
Tested with proactive profile, sandbox disabled.
I don't say that it has to pass all tests but at least the ones which are passed by other products. Matousec has already announced tests on Windows x64, so Comodo should speed up there.
Also, the direct keyboard access warnings are still way to aggressive on x64, it gives warnings if any application receives keyboard input (e.g. typing text). It's only on x64, can't be too hard to fix, reported this long ago.
