Hi,
Following a Bios battery change, my laptop shows the below message when I start the computer (Windows 8.1):
This computer has been disabled using Intel (R) AT.
Intel (R) AT system lock due to :Platform Attack Detected
Time Left to enter passphrase : 897 second
Please select one of the following for platform recovery:
1. - Passphrase
2. - Server Recovery Token
Select one of the above options to proceed...
Invalid Selections, Press 1 or 2
Unlock with Norton Anti-theft http://goo.gl/gccEG
Platform ID : 000033B8
Intel (R) AT service provider ID :15000
How do I uninstall Norton Anti-theft? The software has been uninstalled a long time ago but appears that Norton Anti Theft is still in my system.
I have tried all options including contacting Microsoft technical team (who eventually escalated my problem to their highest technical support level) but they still couldn't resolve my problem.
I've read your forum thread in Norton community that this exact problem was resolved for several users.
Please help.
