Double-click SmitfraudFix.exe
Select option #1 - Search by typing 1 and press "Enter"; a text file will appear, which lists infected files (if present).
Please copy/paste the content of that report into your next reply.

Note : process.exe is detected by some antivirus programs (AntiVir, Dr.Web, Kaspersky) as a "RiskTool"; it is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

Hi, good probably just a little bit left now.
Run part 2
You should print out these instructions, or copy them to a Notepad file for reading while in Safe Mode, because you will not be able to connect to the Internet to read from this site.

Please reboot your computer in Safe Mode by doing the following :
  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  • Instead of Windows loading as normal, a menu with options should appear;
  • Select the first option, to run Windows in Safe Mode, then press "Enter".
  • Choose your usual account.
Once in Safe Mode, double-click SmitfraudFix.exe
Select option #2 - Clean by typing 2 and press "Enter" to delete infected files.

You will be prompted : "Registry cleaning - Do you want to clean the registry ?"; answer "Yes" by typing Y and press "Enter" in order to remove the Desktop background and clean registry keys associated with the infection.

The tool will now check if wininet.dll is infected. You may be prompted to replace the infected file (if found); answer "Yes" by typing Y and press "Enter".

The tool may need to restart your computer to finish the cleaning process; if it doesn't, please restart anyway into normal Windows. A text file will appear onscreen, with results from the cleaning process; please copy/paste the content of that report into your next reply.
The report can also be found at the root of the system drive, usually at C:\rapport.txt



Finally run these
Next run ATF and SAS:

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
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 and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post logs and Let us know how the PC is running now.

Now we will work on the DNS changer,,,,
Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you don’t know the router's default password, you can look it up HERE.


Once you have ran Malwarebytes' Anti-Malware on the infected system, and reset the router to its default configuration you can reconnect to the internet, and router.

Well you sure did well there my friend. I am as happy as you to have been able to get you thru this. You are welcome!

Now 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 backed up, renamed and 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, then 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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

You're welcome. With all the diferent things perhaps being put on and off the PC by the kids you may also want to check for disk defragmentation.
