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 Full 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 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.

I'm here again,
and its taking so long since everytime I restart the PC it takes it about 20 min to come up.
It halts at the first screen right after "MEMORY TESTING:"

But that's a different problem, might yuo be able to help me with that to after the virus is removed.

Just to make sure we are clear, let's do one more malwarebytes scan. Don't forget to update.

Please run the F-Secure Online Scanner
Note: This Scanner is for Internet Explorer Only!
Follow the Instruction here for installation.
Accept the License Agreement.
Once the ActiveX installs,Click Full System Scan
Once the download completes, the scan will begin automatically.
The scan will take some time to finish, so please be patient.
When the scan completes, click the Automatic cleaning (recommended) button.
Click the Show Report button and Copy&Paste the entire report in your next reply.

I would uninstall SuperAntiSpyware. See if that speeds things up.

The things F-Secure found were tracking cookies. You can rerun ATF Cleaner to get rid of those.

If there are no more problems or signs of infection, you should 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.
If you have any further issues, please let us know.
Safe surfing!
