Comodo Internet Security : Comodo Internet Security Pro will get easily killed off by malware if you do not turn on your HIPS manually. I tested it initially with HIPS on, and it passed kill5 test. Then I turned off HIPS module (default setting) and it got killed off easily. It does not protect against executing malicious code through Task Scheduler. On top of that, BITStest has proven that advanced malware will update itself without any issues with Comodo installed.
