BSOD while tryng to uninstall DAEMON Tools Lite

Hello,

Description of the BSOD:

It actually started on 7.12.2014. During that day i had the old installation of Windows that was corrupted by viruses. At first i thought it was virus related. But after i have re-installed Windows 7 x64 Ultimate again (i did a custom install) the issue persisted. The only indicator that something is wrong at first was that as soon as the Windows "Welcome" screen should show up my Monitor had shut down, the PC still worked.

Later i started getting freezes with looped sound when i watched a video with VLC Media Player or on Youtube. During all this time there where no mini-dump files generated. I installed DAEMON Tools Lite yesterday. Then, today i tried to uninstall DAEMON Tools Lite and there was my first BSOD. But the thing is i had DAEMON Tools Lite installed on my old windows install and it did not gave me any errors. Altrough during the installation i chose to install the SPDT Advanced Emulation Driver.
There have not been any other BSOD's so far.

According to BlueScreenView the Problem is:

There are a few possibilities:

1. Open Task Manager. Under the Processes tab, is DTShellHlp.exe still running? If so, then:
- End the process
- Open Device Manager and check under System Devices for an item called Daemon Tools Virtual Bus
- Right click and select Uninstall, then confirm the deletion of the driver
- Go the Daemon Tools folder under C:\Program Files and delete the folder

2. If you still get a BSOD, or DTShellHlp.exe is not shown in Task Manager, temporarily disable AVG, then try uninstalling.

Hello Golden,

Thank you for the suggestions. However, i tired to do exactly as you said multiple times, but it did not work. I cannot find DTShellHlp.exe in the Processes tab. I also cannot find Daemon Tools Virtual Bus under System devices in Device Manager.

I completely uninstalled Avira Free Antivirus and Malwarebytes, and restarted the PC. DTShellHlp.exe and Daemon Tools Virtual Bus still don't show up anywhere. Its weird. Daemon Tools Lite is installed, but it's not active. I have not touched anything within Daemon Tools itself since i installed it.

Please do the following:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Driver Verifier - Enable and Disable

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal and upload the new dmp file/s here.

I recommend creating a system restore point before turning on driver verifier:
System Restore Point - Create

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:
Safe Mode

It's solved! There where no crashes but i was able to remove Daemon Tools after i have disabled driver verifier. It showed up in the Processes tab and then i followed your advice and i used SPTD for Windows (64 bit) to uninstall the SPTD driver, since then no BSOD's.

Thank you so much Golden for your assistance, advice and time! Much appreciated!

Issue with Daemon Tools Lite
I have Daemon Tools Lite on my computer, but the issue is that every time it is used, it checks itself in on the start-up list. I would open MSconfig and it would be checked in again. Is there any way to stop this program from making itself a start-up program every time I use it?
