I ran spybot and it found these 2 files: ackpbsc.dll and snuvcdsm.exe. I deleted them as I was advised. After that, whenever I switch on my computer I get an error message about accrdsub.exe not being able to start because file ackpbsc.dll could not be found. I did some internet inquiry and found out that accrdsub.exe is an application related to ActivIdentity which is supposed to be safe. Do you reckon it's safe to recover ackpbsc.dll?
Concerning the 2nd file snuvcdsm.exe, I am not sure if it is related to the above problem, but is it really malware? Internet information is contradictive.
This link (http://www.incodesolutions.com/threats2/Win32Rootsnuvcdsmexe.php) says it's malware.
But this one (http://www.runscanner.net/fileinfo/snuvcdsm.exe.html) says it has to do with HP Webcam (I have HP with inbuilt webcam).
I don't know what to trust. Can anybody help please?

If the file is good or not sometimes depends on where the file is located. Usually those sites should give you a path like : c:\windows\system32\filename.com See if that matches up to the file you are seeing.

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Before I carry on with that process.....
I dont believe that there is any malware in my computer anymore. The question is: should I restore ackpbsc.dll or not? It is also under the Virtumonde.sdn (in spybot) title and it was stored in C:\Windows\System32\ackpbsc.dll as a Library file. Thanx for responding

Welcome back Ket,

The file is in the wrong location. Please submit it to Jotti's and post back the result.

@ AndreC I am going to split your post from this topic so it can receive individual attention

But how can I send the file since it has been fixed by spybot? The only way would be to restore it but that could be very risky, no?

No, if it is gone, leave it gone.

Still, I would run the Malwarebytes scan and check for the file - just in case. Vundo is a very hardy infection and usually deosn't go away easily. If you are sure that everything is gone, I would flush system restore.

Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.

Hi. Thanx again for the advice. Do you reckon if I run the malwarebytes scan it can solve the problem? The problem is that the application accrdsub.exe, which is related to ActivIdentity, wont start because the ackpbsc.dll file is missing, resulting the error message I explained in my first post. I looked on how to reinstall it but the information given (by actividentity's folder already in my computer) doesnt coincide with what I see in my computer. To begin with, there is no ActivIdentity in the programs list in the control panel, so I cannot repair. There are ActivIdentity folders though in my Program Files. I have vista premium and maybe the instructions should be different. (Saying that, it also applies to the instructions for system restore as I dont get the "more options" tab). I also dont find any installing application. Any ideas?

Hi,

I also found ackpbsc.dll and snuvcdsm.exe with Spybot, and deleted them - and got the same ActivIdentity error messages as Ket wrote in the original post. But now I restored the first of them, the error messages went away, and the Jotti's and Malwarebytes suggested here by rigel don't show any problems.

Hmm, did Spybot give us a false alarm about ackpbsc.dll? :thumbsup:

And what about the second file, snuvcdsm.exe? I'm not sure yet...

Hello again. Thanks everybody for your interest. I did system restore and everything seems to be back in place. I scanned the 2 files with Jotti's and nothing was found. I even found the spybot recovery folder (see below) and scanned (Jotti's) the zipped virumonde files and nothing was found again. It seems it was indeed a false alarm from spybot. So I will close for the moment. Thank you again.
