I believe I'm having the same problem. My first reboot after installing anti-theft, my computer will not successfully boot. During the Windows 7 startup screen, before the user is selected, the whole screen flashes and appears to restart the Windows boot process, and repeats about every 1 second. I can successfully login to Safe Mode with Networking, see both my normal and alias logins, but it's in safe mode. I tried to run ESET Smart Security, but it will not startup in Safe Mode. What should I try?
I'm running Windows 7 SP1 on an HP 4540s laptop. ESET Smart Security was recently installed, scan was run, minor issues were found and corrrected.
