Below is a partial log of Rootpeal's scan of Stealth Objects. The obvious concern is those unusual characters in the entries. For the "a4x3rd9u" entries, it's a different name with each boot-up, always starts with "a" and 8 characters in length. I have ran many different programs including GMER, Radix, HJT to scan the system, and found nothing else obvious. "a4x3rd9u.sys" is supposed to be in Windows\system32\drivers, but it's not there, so I guess it's hidden. Radix under Module scan showed "a4ux3rd9u.sys" as "signed", I don't know if I am correct in assuming a "signed" file is supposely okay. I already submitted "Cdfs.sys" to Virus Total and it's not infected. I am concerned there's yet another hidden program creating "a4x3rd9u" with each boot-up. Finally I like to mention that those entries are not present in Safe mode.

Rerun it ,, Under scan select only Files.

Also please run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link 2

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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

I thought of something that happened before with Daemon Tools, so I uninstalled Daemon Tools and deleted SPTD.sys. There's now no entries under Stealth Objects or Files. So all these again caused by Daemon Tools.
