The question is is it still possible to someone to launch the computer without this exe running?
1.he can enter to safe mode and delete the entry of the registry, so how can i set the exe to automaticlly launch also in safe mode?
2. He can enter to the computer with a linux installation, and delete the entry from the registry, and also delete the exe itself

The question is how to protect that a maximum. I know that there wil be always someone who will find a trick i didn't think about it, but how can i protect this a maximum.
Thanks
