A driver has requested that an IRP be completed (IoCompleteRequest()), but
the packet has already been completed. This is a tough bug to find because
the easiest case, a driver actually attempted to complete its own packet
twice, is generally not what happened. Rather, two separate drivers each
believe that they own the packet, and each attempts to complete it. The
first actually works, and the second fails. Tracking down which drivers
in the system actually did this is difficult, generally because the trails
of the first driver have been covered by the second. However, the driver
stack for the current request can be found by examining the DeviceObject
fields in each of the stack locations.

it has to be the problem of the software, I used to get BSOD quite often like after 2-5 mins after just turning on my computer. It was because of the RAM, I had 4 GB RAM DDR2, but I only have 2 GB RAM and the extra DDR2 stick has gone for repairs .
So, I am guessing that its the problem of the software you have (webroot security scanner)
