I do not agree with the statement “TNR Utilities is the perfect line of defense against users using your equipment malicously.”.
I tested this tool and blocked notepad.exe, and yes, starting of notepad.exe was not possible anymore. But after renaming notepad.exe to notepad1.exe this application was able to run again, of course with process name notepad1.exe displayed in the taskmanager. So anybody who can change the file names can circumvent this protection.
It should be rather the opposite way: this tool should prevent the execution of any process except for a list of allowed processes (white list). And to prevent that a malicious user just renames e. g. virus.exe to e. g. notepad.exe (or any process on this white list) it should also document the hashes (e. g. md5) of the allowed processes.
I uninstalled the tool again, no value add for me.
We were thinking of taking an approach that would go off a whitelist, however, this could be very dangerous as if Windows were to update their OS, our program could potentially block a critical process and brick someone’s computer. Since we aren’t an antivirus, it would be extremely difficult to check if the user just changed their name and what-not. I will be the first to admit that our program is weak in that department, however, the usage policies section is our absolute strong point. We are sorry you feel this way and we hope you find some value in our product in the future.
