I have used this tool in the past and is a great freebie to run on any prolematic system,
Dont expect the world of this program cuz at the end of the day it's free and anything that's free is not always that comprehensive at scanning but this in combination with Malware bytes and trend micro and you can't go far wrong.
P.s: Anyone that has a system causing blue screens and your about to give up and rebuild your systems then STOP!!, Try poping in the HDD into another system as a slave.
Obiously you need to ensure your MASTER machine has full Anti virus and firewalls enabled which are all up to date, and that you lock of the possiblitly of anything writing to your MASTER systems main drive, McAfee's Access Protection comes to mind
This stops the nasty malware/virus from jumping from one HDD to another and is ususally the quickest clean up option for me rather than trying to rollback or re-install the OS or APPS.
