{STATUS_DEVICE_DATA_ERROR} Boot-time scan problem

Hi all,
just wondering if anyone had seen this problem I’m running into.
Just downloaded windows 8 on my HP Touch Smart 520 PC
I’m using Avast 7.0.1474. The boot time scan I ran gave me this message every time something was detected:
File C:[whatever] Error 0xc000009c {STATUS_Device_DATA_ERROR}
has anyone had this issue? Any ideas on how to resolve this?

did your HP come with a preinstalled AV?......hp often have a trail version of Norton installed!

did you uninstall it before installing avast?
did you run norton removal tool to clear any leftover files that may conflict?

googel search on your error code
