nod32 freezes when I enter the password (by paste or typing)

problem:

nod32 many times doesn't accept the key, as the egui.exe process freezes consuming 100% of the cpu.

solution:

do not wait... and do the follow
- kill the process from task manager
- run again the nod32 antivirus
- open it and go from its menu Setup -> Setup username and password
- enter now in this dialog the user name and the password; from this way the nod32 doesn't freeze.
