Cable Forum - PC Freezing. ZA Pro V.5 ?

For the past week or so my PC ( Win XP Home) has been freezing. It is a random occurrence, has happened about six times. I strongly suspect the latest Z Alarm Pro update to version 5. Looking on their forums would suggest large numbers of people are having problems and the only advice seems to be to uninstall and reinstall V4.5. I don't want to have to go through all my settings in ZA again, so I am putting this off for the moment.

The mouse freezes and no keystrokes work, even Cont+Alt+Del has no effect.
I have to press the reset button to clear, it reboots perfectly without any warning that it has been shut down incorrectly, however on 3 out of the 6 times after pressing reset the GUI for Z Alarm is open on the desktop, even though it was not in use before the lock up.

All AV/Adware/Spyware scans are clean.

I have attached a screen grab of Task Manager and also a Hijackthis logfile.

Can anyone see anything that may be causing this other than Z Alarm Pro V.5?

Logfile of HijackThis v1.97.2
