Look'n'stop blue screen

[google]

I have some trouble with look'n'stop, it randomly restarts computer or generate blue screen. I'm sure the problem is lnsfw.sys. After two or three hours maybe less a blue screen appears even if i do nothing at that moment.
My system is windows xp sp2. I think the only incompatibility may be with Kaspersky Internet Security 2006 which i have installed.
I attached a log generated with Debugging Tools for Windows and two of the minidump's files (change extension of attachement from .txt to .rar)
Can someone help me or maybe a sugestion ?

I've already seen a similar case before.
Send me an email at lnssupport@soft4ever.com mentioning the version of Look 'n' Stop you are using, and I will send you a special driver for testing.

Thanks,
