When you get a message that the system is shutting down, follow these steps to stop the cycle:
  • Click on Start > Run and type: cmd
  • Press Enter.
  • At the Command Prompt type: shutdown -a
  • Press Enter.
or Click on Start > Run and type: shutdown -a
Press Ok.

Then please download Malwarebytes Anti-Malware (v1.32) 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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.

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes. Click this link to see a list of programs that should be disabled.

Thanks for the reply. As for this part, i actually don't have enough time to do this because the system begins to shut down in less than a second. I did the MBAM thing and the scan said that there were no malicious items detected.

If you're using Windows 2000/XP, please print out and follow these instructions: "How to use SDFix". <- for Windows 2000/XP ONLY!
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • Please be patient as the scan may take up to 20 minutes to complete.
  • When the process is complete, the SDFix report log will open in Notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • The SDFix report log (Report.txt) will open in Notepad and automatically be saved in the SDFix folder.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to re-enable you anti-virus and and other security programs before connecting to the Internet.

I downloaded SDFix "RunThis" file, but it restarted my computer. The same dialog box popped out saying the system will restart in 1 second. It seems like everytime i try to access DOS my pc would restart.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your log in the thread titled "Post in this thread when you haven't received an answer in five days.".

Anything thats access command prompt/dos shuts down my pc. I asked help here http://www.bleepingcomputer.com/forums/t/194142/cmd-restarts-my-computer/ where quietman7 told me to use SDFix, but even using SDFix shuts down my pc.

I downloaded the DDS stuff from here http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/, but my pc recognizes it as an "AutoCAD Scrpt" file.

Help would be greatly appreciated.

Hello Kim.Nejudne,

I have merged the topic you posted in the HiJack This forum here to your previously existing topic in the Am I Infected forum as you didn't post any logs.

Since you were unable to run DDS, see if you can do this:

Download RSIT by random/random and save it to your Desktop.
Note: You will need to run this tool while connected to the Internet so it can download HijackThis if it is not located on your system. If you get a warning from your firewall or other security programs regarding Rist attempting to contact the Internet, please allow the connection.
  • Close all applications and windows so that you have nothing open and are at your Desktop.
  • Double-click on RSIT.exe to start the program.
  • If using Windows Vista, be sure to Run As Administrator.
  • Click Continue after reading the disclaimer screen.
  • Leave the drop down box set to default: "List/folders created or modified in the last 1 month (30 days).
  • When the scan is complete, a text file named log.txt will automatically open in Notepad.
  • Please start a new topic and post your log in the HijackThis Logs and Malware Removal forum, NOT here.
  • Be sure to mention that you tried to follow the Prep Guide but were unable to get DDS to run.
If RSIT did not work, then reply back here.

Ah, good Kim.Nejudne. I see you were successful in running RSIT and posted your log here: http://www.bleepingcomputer.com/forums/t/198754/entering-command-prompt-shuts-down-my-pc/


Now that it is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.
