Hi FHiL

You aren't running Anti Virus Software. Please download and install one of them first!!!

Use an Anti Virus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future. Here are some Anti Virus products which are free for personal use and most used:
AntiVir
Avast
BitDefender

Update your Anti Virus Software - It is imperitive that you update your Anti virus software at least once a week (Even more if you wish). If you do not update your anti virus software then it will not be able to catch any of the new variants that may come out.

As you did this, we can begin with the fix.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible.
Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

1 - Download and Install SDFix
Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

2 - Boot into Safe Mode

Reboot your computer in Safe Mode.

• If the computer is running, shut down Windows, and then turn off the power.
• Wait 30 seconds, and then turn the computer on.
• Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
• Ensure that the Safe Mode option is selected.
• Press Enter. The computer then begins to start in Safe mode.
• Login on your usual account.

3 - Run SDFix

• Open the extracted SDFix folder and double click RunThis.bat to start the script.
• Type Y to begin the cleanup process.
• It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
• Press any Key and it will restart the PC.
• When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
• Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
  (Report.txt will also be copied to Clipboard ready for posting back on the forum).

4 - Download and Run VundoFix
Please download VundoFix.exe by Atribune save it to your desktop.

• Double click VundoFix.exe to run it.
• Click the Scan for Vundo button.
• Once it's done scanning, click the Fix Vundo button.
• You will receive a prompt asking if you want to remove the files, click YES
• Once you click yes, your desktop will go blank as it starts removing Vundo.
• When completed, it will prompt that it will reboot your computer, click OK.
• A log will be saved here: C:\vundofix.txt

Note: It is possible that VundoFix encountered a file it could not remove. In this case, VundoFix will run on reboot, simply follow the above instructions starting from "Click the Scan for Vundo button." when VundoFix appears at reboot.

If you receive this error - "Run-time error '339': Component 'comdlg32.ocx' or one its dependencies not correctly registered: a file is missing or invalid" , please download this file and save it to your desktop.

• Right click on Comdlg32.zip and select Extract All....
• Click Next on seeing the Welcome to the Compressed (zipped) Folders Extraction Wizard.
• On the text box above the Browse button, copy and paste in C:\Windows\system32.
• Click OK.
• Uncheck (untick) the Show extracted files box and click Finish.
• Click on Start > Run and copy and paste in the following into the Run box:
  
  REGSVR32 C:\Windows\system32\comdlg32.ocx
  
• Press Enter.
• You should receive this message - DllRegisterServer in C:\Windows\system32\comdlg32.ocx succeeded.
• Click OK and restart your computer. Then try running VundoFix again.

5 - Status Check
Please reply with

1. the SDFix Report.txt
2. the Vundofix.txt
3. a fresh HijackThis log
