Hi All

I am running ESET Smart Security 4. On scans, it quarantines ddcYrRki.dll which if finds in the C:\Windows|system32 folder. When I search on their website as well as the CERT virus db, it does not show up anywhere. If I search the entire internet, I only get 1 result for a site which has prevx in its url, which is suspect is a scam.
I did a search in the registry and found it in the registry at HK_Classes_Root->CLSID->{....}InprocServer32.
In that was: Default Reg_SZ C:\Windows\system32\ddcYrRki.dll.

Since I can't find info anywhere, I assume it is not a process I want running, but I hesitate to delete it from the registry.
Any info would be greatly appreciated.

Generally, when a Google search shows up very few results for a file name it's most likely malware.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
The power of accurate observation is commonly called cynicism by those who haven't got it.

Thank you Budapest - I followed your directions and MalwareBytes got rid of multiple files and registry entries that my av hadn't found. I have run it twice more as well as my av and it looks like it is gone. Thanks :thumbsup:

These files are now in quarantine. I wanted to check with you before I remove them, as they look like they might be needed. Or are they remnants of the virus?

Those are most likely remnants of the virus and can be removed.

Thank you so much for your help. I let the scan run to completion, then let it delete those files. I have run the scans again, and nothing was found by any of them.

Thanks again for getting me out of computer hell :thumbsup:

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go 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 Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.

Also, go Start > Control Panel and double-click Add or Remove Programs. Post back and report any Java entries that you have.
