Virus or not?


I installed Daemon Tools 4.0 on my computer and immediately got the warning from RegRun.

VVSN.EXE process was started and added to the Windows startup registry keys.

VVSN.EXE is identified as Adware and it was removed without problems.

But what is the strange driver SPTD9885.SYS? It contains no version information.

But I guess that it is related to Daemon Tools software.

Recently I see a lot of user requests for similar driver names.

Looks like Daemon Tools makes the random name for driver with "SPTD" + random 4 digits.


SPTD####.sys is not a virus and it is not dangerous.

But it is not a finish of the story.

I uninstalled Daemon Tools software using Add/Remove Programs in Control Panel.

I checked the Drivers list and I found that SPTD.SYS and SPT9885.SYS still work in memory.

I opened regedit.exe and looked for SPTD subkey in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services.

I could not delete this subkey. And I could not read the contents of the SPTD\CFG subkey!

I made right click on the SPTD subkey and selected "Permissions" in the popup menu. I see that the Administrators group have no rights for deleting or changing.

I deleted the SPTD.SYS file from the C:\Windows\System32\Drivers folder and rebooted my computer.

After that I checked the Drivers list to be sure that SPTD.SYS has gone.

Good news! SPT9885.SYS has gone too!

Now I can see the contents of SPTD\CFG subkey.


  1. SPTD.SYS executes SPTD9885.SYS;
  2. SPTD.SYS hides the contents of SPTD\CFG subkey;
  3. SPTD.SYS protects the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SPTD from chaging by using registry permissions.
If you don't use Daemon Tools - remove SPTD drivers.

They are useless for you!

Removal Procedure:

  1. Delete SPTD.SYS from the C:\Windows\System32\Drivers folder.
  2. Reboot.
  3. Delete SPTD9885.SYS or the driver with similar name from the C:\Windows\System32\Drivers folder.
  4. You may use RegRun Registry Assistant to delete protected keys without problems.
    Or use regedit.
    Go to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SPTD.
    Right click and choose "Permissions" in the popup menu.
    Change the rights for Adminitrator group to Full access.
    Delete SPTD subkey.
    Do the same for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SPTD.

Use RegRun!

They say
"RegRun Security Suite is one of those very rare tool kits that no one who is serious about protecting their PC should ever be without. This toolkit covers all the bases when it comes to eradicating the attempted security threats from malware that we all face - daily. The near real time tech support, direct from Greatis, is nothing sort of superb, something that can be rarely said these days! I have no hesitation in recommending this suite to anyone."

You guys are awesome!!!!

Bob Schmulian:
Absolutely love it and have recommended to many people!

Ian Robinson:
It is FANTASTIC! It has saved my life on more than one occasion since I purchased it less than 6 months ago. I now would not run my system without it... it's worth many times the cost! The service and support are terrific. Helpful - friendly - and accommodating; and generally a reply is received within 12 hours. Just great.

Theodore Soucie:
Since RegRun was installed my system is more stable. I use to experience freezeup daily. I have not had a crash.
