Please help,

My computer has been fine the past few weeks of me using it pratcially everyday but in the past couple of days it's been BSOD'ing EVERY time I shut down or reboot.

I am running Windows Professional x86.

Any help or advice is greatly appreciated and my apologies in advanced if this is the wrong procedure in requesting for BSOD analysis and help.

Thanks again.

Here are the last three dump files.

Anybody?

It looks like the problem is caused by the file klif.sys. This is a Kaspersky Anti-virus file. I would try updating the software. If that does not fix it, you may want to uninstall then reinstall Kaspersky.
