You wil need to update and rerun MBam..
Rerun MBAM (MalwareBytes) like this:

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


Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

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.



It attempts to spread to removable drives by creating an autorun.inf file, which will run the worm automatically, if a systems which use the removable drive are set to Autorun. There fore You should run this on any Flash Drives that were connected to this PC and then any PC's.
Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.


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

Thank you boopme for your reply.

I updated MBAM many times, and then I scanned the computer, but every time I was getting those same errors. Then I scanned with SAS. Here is the old report:

This looks good. After you've run FD. Please do an online scan so we are sure.

ESET
Please perform a scan with Eset Online Antiivirus Scanner.
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista users need to run Internet Explorer as Administrator. Right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run as Administrator from the context menu.
  • Click the green ESET Online Scanner button.
  • Read the End User License Agreement and check the box: YES, I accept the Terms of Use.
  • Click on the Start button next to it.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then click Insall ActiveX component.
  • A new window will appear asking "Do you want to install this software?"".
  • Answer Yes to download and install the ActiveX controls that allows the scan to run.
  • Click Start.
  • Check Remove found threats and Scan potentially unwanted applications.
  • Click Scan to start. (please be patient as the scan could take some time to complete)
  • If offered the option to get information or buy software. Just close the window.
  • When the scan has finished, a log.txt file will be created and automatically saved in the C:\Program Files\ESET\ESET Online Scanner\log.txt
    folder.
  • Click Posted Image > Run..., then copy and paste this command into the open box: C:\Program Files\EsetOnlineScanner\log.txt
  • The scan results will open in Notepad. Copy and paste the contents of log.txt in your next reply.
Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

I have dial-up internet connection, and it is taking forever to download and to scan with Eset Online Antiivirus Scanner.

Is there any other way to scan the computer?

Well update and rerun MBAM? You did FD?
Update and run Your Antivirus also.

I have scanned with SAS, MBAM, and AVG free version and found nothing.

Yes I did run FD, and just got the OK message.


I think my computer is safe now, What do you think? Do I need to check with any other antivirus program? If NO, you can close this thread and thank you very much for your help.

Hi, I think we are good here...
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 and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
