I have positively identified ZoneAlarm version 6.5 as the cause of my BSOD (Blue Screen of Death) after Check Disk. I have also observed this on two other computers other than mine.
NOTE: Version 6.5.714.000, released today (June 15, 2006), DOES NOT resolve this problem, and the other problems I describe below.
Even the ZoneAlarm Free 6.5 (firewall only), causes the BSOD after Check Disk.
*** STOP: 0x00000071 (0x00000000,0x00000000,0x00000000,0x00000000)
After this BSOD, the only option that works is to boot with "Last Known Good Configuration".
Other problems I have noticed caused by ZA 6.5:
1) Eudora fast search indexing interfered with (X1 search).
2) During shutdown of Windows, ZA does not shut down properly, and continues to write to the Windows Registry while the computer is shutting down.
Until Zone Labs have solved these problems, I recommend that everyone uninstall version 6.5, and install the last known good version, 6.1.744.001.
