When posting your problem, do not run and post a ComboFix log. ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer. Any posts containing CF Logs will be ignored.

To receive help, you should instead provide a detailed description of your problem, detailed word-for-word error messages that you are receiving, screenshots of strange behaviour, and your operating system. This information is much more useful to our helpers than a ComboFix log.

Whatever you do, don't follow that program's advice. It's the real virus.

Run Malwarebytes in safe mode (keep hitting F8 on restart). It should fix your problem. If not, look for a manual removal here.

How to start Windows 7 in Safe Mode


Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.

    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select FULL scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Arrrrgh! The Win 7 Anti Virus nonsense is gone, but I am getting random search results when I type stuff into Google. This happens in I.E. and Firefox. So frustrating! How do I fix this?

Please download TDSSKiller.zip and and extract it.
  • Run TDSSKiller.exe.
  • Click Start scan.
  • When it is finished the utility outputs a list of detected objects with description.
    The utility automatically selects an action (Cure or Delete) for malicious objects.
    The utility prompts the user to select an action to apply to suspicious objects (Skip, by default). Let the options as it is and click Continue
  • Let reboot if needed and tell me if the tool needed a reboot.
  • Click on Report and post the contents of the text file that will open.

    Note: By default, the utility outputs the log into system disk (it is usually the disk with installed operating system, C:\) root folder. The Log have a name like: TDSSKiller.Version_Date_Time_log.txt.




If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to these[/color] instructions. In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.
