I've had this thing bugging me for a while and need help removing it. At first it would prevent from viewing certain sites (adult ones) which would tell me i had a Rustok/trojan virus however this has now stopped and i can't remember if it was telling me i had Rustok B or N.

As far as i can tell it is preventing my Norton anti-virus from running (my weekly automatic scan opens but its unable to search at all, i am unable to close it) Most links on google redirect me the first 2 times i attempt to load them to varying sites and its slowed my computer substantially.

I'm running Vista Version 6.0.6001 Service Pack 1 Build 6001

I've tried to follow all the rules of bleepingcomputer as well as possible but if there is anything I've missed i'm sorry and if you tell me i'll edit my post appropriately.

Welcome to BC


The process of cleaning your computer may require you to temporarily disable 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 Free version and save it to your desktop.

NOTE: Before saving MBAM please rename it to zztoy.exe....now 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.
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
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

I can't get any of the links for the Malware bytes to work, I'm fairly sure the virus is blocking the sites. I'll try to get it on usb off a friend but if you had any alternative links that might work that would be greatly appreciated.

You renamed Mbam.exe, correct?

Try running rkill before mbam
It might need to be run multiple times


Please download Rkill by Grinler and save it to your desktop.Link 2
Link 3
Link 4
  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista, right-click on it and Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
Do not reboot the computer or you will have to run it again

Its not running the MBAM i'm having trouble with, I can't actually find a link to malwarebytes to download it that works. The pages are all instantly going to "Page cannot be displayed" by how quickly it happens i'm assuming its the virus/whatever it is thats blocking it.

Can you use another computer and download it to a thumb drive?


Here's all the tips I have for Mbam:


Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe. If that did not work, rename it explorer.exe.
  • Double-click on the renamed file to start the installation.
  • If that still did not work, then try changing the file extension. <- click this link if you do not see the file extension
    If using Windows Vista, refer to these instructions.
  • Right-click on explorer.exe and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on explorer.com (or whatever extension you renamed it) to begin installation.
Note: Malwarebytes Anti-Malware uses Inno Setup instead of the Windows Installer Service to install the program. If installation coninues to fail in normal mode, try installing and scanning in safe mode. Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe and rename it to wuauclt.exe.
  • Double-click on wuauclt.exe to launch the program.
  • If that did not work, then change the .exe extension in the same way as noted above.
  • Double-click on wuauclt.com (or whatever extension you renamed it) to launch the program.
If that does not work, you can try using Rkill before scanning with Malwarebytes Anti-Malware. This tool terminates certain processes and fixes certain registry keys that stop us from using security and clean up tools. Please download Rkill by Grinler and save it to your desktop.Link 2
Link 3
Link 4
  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista, right-click on it and Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • Do not reboot until after scanning with Malwarebytes Anti-Malware.
-- Other types of malware may delete the main mbam.exe executable file during installation or when attempting to perform a scan which results in various errors such as code 2...The system cannot find the file specified or mbam.exe - Application error.

One way to resolve this is to download and install Malwarebytes Anti-Malware on a non-infected computer.
  • After installation, open Windows Explorer and navigate to the C:\Program Files\Malwarebytes' Anti-Malware\ folder where mbam.exe is located.
  • Copy the mbam.exe file to the Desktop and rename it to wuauclt.exe or explorer.exe.
  • Save the renamed file to a usb flash drive or CD, then transfer to the infected computer.
    • Alternatively, you can download a randomized renamed mbam.exe version (i.e. jdRjuT7Hk.exe) from here and use that.
    • Another option is to upload the file somewhere so you can download it later to the infected computer.
    • If you do not have access to another computer, ask a friend to email or upload a renamed mbam.exe for you and provide a link to download it.
  • Place the renamed mbam.exe in the C:\Program Files\Malwarebytes' Anti-Malware folder on the infected computer, then double-click on it to launch the program.
  • Check for database definition updates through the program's interface.
  • Then perform a Quick Scan, check all items found for removal and reboot afterwards.
  • Failure to reboot will prevent MBAM from removing all the malware.
  • When done, click the Logs tab and copy/paste the contents of the report in your next reply.
Another thing you can try, if you cannot run MBAM or complete a scan in normal mode, is to perform a Quick Scan in "safe mode".

Scanning with Malwarebytes Anti-Malware in safe or normal mode will work but removal functions are not as powerful in safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, MBAM loses some effectiveness for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. Additionally, there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM but sometimes there is no alternative but to do a safe mode scan. If that is the case, after completing a safe mode scan, reboot normally and try rescanning again.

Before performing a scan, don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

If you cannot update MBAM through the program's interface and have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page, be aware that mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating, is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.
  • XP: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware
  • Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware
Additional Note: Some infections will alter the Proxy settings in Internet Explorer which can affect your ability to browse. To check those settings, please refer to Steps 4-7 under the section Automated Removal Instructions...using Malwarebytes' Anti-Malware in this guide.

Ok i ran Rkill.exe, copied the mbam.exe onto my desktop (named as zztoy.exe) and i get this error.

16 bit MS-DOS Subsystem

The NTVDM CPU has encountered an illegal instruction.
CS:11ea IP:010a OP:63 20 4f 53 20 Choose 'Close' to terminate the application

It won't let me rename it to any of the other names because it says the program is already in use as well.

Lets see if we can get you preped to submit a DDS / HJT log
Follow these instructions
If you have problems post back here. Otherwise go ahead and submit the logs



Please read the pinned topic titled "Preparation Guide For Use Before Posting A DDS / HJT 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 Malware Removal 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 Malware Response 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.

The MR team is very busy and it will take awhile to get to your post
Please be patient and good luck
