Hi,
I noticed that my 11-year old suddenly could access his account at times outside the curfew.
When pressing him about it, he told me he had "cracked Norton". It turned out that all he had to do was to kill the nf.exe process.
When killing it the first 3-4 times, the process would automatically restart (reappear in the task list). But after that, it was gone for good.
He is standard user at windows 8.1. I just reinstalled the most recent version of the program as Administrator. But I can still reproduce it easily, from his account, only using his own password. I am typing this now from his account at 22:24 local time, which you will appreciate is outside his curfew time.
A quick correction would be most welcome..
