Daughter has once again managed to infect the computer with some trojan anti-virus type thing, but this one has messed things up really bad. I have been through this sort of thing several times over the past 5 years or so, so I attempted to resolve it myself. Somehow this one manages to interfere with the file system, so I am unable to see pretty much anything on the computer, (hopefully it's all still there), I tried to run combofix, I know you guys don't like that, sorry... with some infections that is the only thing that will remove enough of the infection to get anything else to run. In any case combofix failed to run anyway. I used rkill and I was able to get superantispyware to update, and then, after rebooting, I was able to run it and it detected what it called a vundo variant, and claimed to remove it. We were getting popups about a damaged file system, and some sort of windowssystemrestore program that was running fake scans and listing all kinds of problems, those have stopped since the superantispyware scan, however our desktop is still blank, and anything new placed on it is not there after rebooting, our program files list is blank, the recently used programs list is blank. If I try to go into my computer and click on a drive, it just lists the folders created by combofix and vundofix (I attempted to run vundufix after the superantispyware scan to see if it could help, but it didn't detect anything) I will include the scan log from superantispyware

If someone could help me, I'd rather not have to restore this system, I'm not even sure where the discs were put since the last time I used them was before we moved here almost 2 years ago.

Rerun RKill and immediate run MBAM

Do not reboot until after MBAM.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.
