OK, but it´s not solving the complete problem. I restored the file from the Norton quarantine but Norton has stored the file not in the right folder. And the folder where it should be is not exisiting anymore. Result: Autostart of enpass is not working. How i can fix this? Update: OK the folder exist, only viewable when i change the view options in Explorer (hidden/system). But the folder is restricted, i give me full rights to the folder but i can´t copy the EnpassStartup.exe to the folder.
