Great review, and its good to see that Comodo made some progress.
Also as you said the direction they are going is good... so I hope they can keep it up.
Little critical note, I am not to impressed with the blocking feature for one reason alone, during the execution of some of the files you could see in killswitch that some made like 5 or 6 processes and Comodo caught only 1.
This technique used in malware development to fool the AV and to inject malicious code into legit processes.
And even tho Malwarebytes and all other programs did not detect any afterwards I would bet that a full scan on max settings would turn up a few hidden ones.
Another thing I want to mention CIS told you to restart the PC because a few files where still "active" even tho they where quarantined.
This should NOT be possible. If a file is quarantined it should not be able to run, and CIS should have enough admin rights to KILL the PID and take the file out of the system into the quarantine.
I personally know some Malware that if CIS would perform in the same way, they would totally destroy your OS.
That said all in all I think its a nice suit and its good to see that they are moving forward.
Great review and thanks.
