  1. Does comodo protect against files, which get inserted in place of formerly allowed files?

  2. What can comodo hips protect against if someone tries to use the pc while windows user password is set (admin account + NO user account, or in case of both present)? What about the bypass password ways?

  3. Does comodo store its password in an accessible way?

The plan is to use comodo hips with password, set alarms to be hidden. The goal is to have a save computer while it is on its own. With no changes happening.
