Hi, Folks,

We received several new pre-loaded laptops recently that apparently had a worm on them. The worm places the text "Bertakwalah kepada Alloh dimanapun kau berada" in the title bar on Internet Explorer. I was told to run ComboFix.exe to correct this problem, which I did. This fixed the problem. Is there any need to post the various logs to this site for possible further action?

Many thanks.

We cannot assess ComboFix logs in this forum. Those logs can only be used in our HJT forums - sorry. if you wish, you could run a scan with Malwarebytes to see if anything further is found.

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.

  • 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 Quick 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.

Note 2:
-- 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. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Actually this is an automated script which is applied in your system. For removal of this please follow the following steps -

1. Open My Computer > Tools > Folder Options > View
2. In Advanced Settings select "Show hidden files and folders" and remove the checkmark from "Hide protected operating system file (Recommended)", Press OK for the warning message.
3. Open all system drives one by one (example C:, D; etc) and delete autorun.inf and any file with 'vbs' extension.
4. Delete the same vbs file from C:\Windows folder also.
5. In case you are unable to delete the vbs file then kill the wscript.exe process from task manager
6. Open Reg editor and navigate to Hkey_users > S-1-5-21-1244467668-1331586020-26564730-50773 > Software > Microsoft > Internet Explorer > Main
7. On the right pane dbl clk the Window Title and type "Microsoft Internet Explorer"
8. Exit registry editor

your issue will be resolved...atleast this worked in mine system...:thumbsup:

What works in one system, may not work in others. Also suggesting registry edits without first giving instructions for backing up the registry is dangerous.

Please post the requested logs and we can go from there

My apologies for not letting the user know how to take the reg backup, but if you see carefully the registry changes that i have suggested are only for changing the IE Heading. This solution worked in 5 more systems here in my office from where my system got affected. :thumbsup:

Actually the file "sgt.sys.vbs" is the culprit who copies itself into root of local drives and windows folder. Also you will find nothing in the logs as i have installed this crap software in my system and it returned nothing. If you want those files I can send it to you, but it will be of no use to you as i have already sumitted it to McAfee and their new DAT is expected very soon... :flowers:

Please let me know if you need any kind of help or information from my side so that we can make Internet a good place to live
