Threatfire installation over PrevX.

This time I have a problem maybe not on PrevX but on Threatfire's side...
but maybe it'd be better to inform PrevX first.

here's what happened:
PrevX and threatfire installed consecutively. (PrevX first, threatfire last)
Threatfire prompt me for a reboot. So I reboot.
On startup, all system tray icons loaded except PrevX and Windows XP Freezes (all I can do is move my cursor. can't ctrl+alt+delete too)

I waited for 3minutes or so... Its still frozen!!
so I press the reset button.

now everything is working fine... PrevX starts up fine and it immediately shows the authenticating window and scanned Threatfire files.

I looked at Event viewer and this is what it shows.

I also attached the scan logs.

Also.. there is no other security programs installed other than those 2 I've mentioned.



EDIT: I gave up on threatfire just now... it always bring troubles. XD
