Trusted bad is less of a problem than what legacy AVs do which is allow an unknown to run.
No system is 100%, its all about the best solution not perfect, because perfection doesn’t exist.
By the fact Comodo has serious vulnerability bugs and now is possible to run (or download and run) unknown application (even malware) bypassing all layers of Comodo security. I hope next update planned on March fix these bugs.
Hopefully Comodo regularly maintains it’s “Safe List” and removes bad vendors/files, I think Advanced users of Comodo should be given more controls over the Trusted Files, both locally safe by TVL and by cloud list.
