I don't know if this is a bug or not, but when I try to run an unknown file as trusted through right click options, the unknown file will install as normal, even though it was blocked from executing because of my sandbox settings to run only safe applications. My settings is password protected, therefore I thought that it should be password protected when I try to run an unknown file as trusted, for security reason. If this is really the case, anyone using my computer can simply run an unknown file by right clicking it, then run as trusted without any password prompt. Is this how the comodo cloud antivirus works? Thanks very much in advance.
