I have installed ZA free Antivirus and Firewall. After the reset, OS launches with a blue screen with amppal.sys details.

I would attach the dump file of the BSOD, but it says it is invalid file upon upload.

I suspect the Intel Centrino Wireless Bluetooth 3.0 got screwed by this install.

I there any preceding problem with this service?
