I am in the process of cleaning up a friend's laptop which was heavily infected with a variety of malware.
After installing and running Windows Defender, Windows Security Essentials, Spybot S&D and Antimalwarebytes the computer started freezing up. Eventually Windows Defender reported that its service had stopped and on trying to restart it, I encountered the BSOD.
On the next reboot, I encountered the BSOD which flags ndis.sys as the culprit.
I can access windows in safe mode (without networking) and have completed the cleanup with the above tools. However as ndis.sys is the network discovery interface, I am unable to connect the machine to the internet in order to update the driver.
I also would like to confirm it is not a virus, although currently the above tools all report the machine as being clean. I find it is strange that the BSOD only occurred after installing and running the anti-virus programs, so I was wondering if there might be a conflict with something nasty embedded a little deeper.
Your help is greatly appreciated.
