I think I have a virus in a computer. I can't run antirootkit programs, I can't go to some antivirus websites (the browser closes), and it has disabled my antivirus.
Can you help me?
I'm using Windows XP SP2 32-bit.

First, Download rkill.com to your desktop.

Double-click on the rkill.com in order to automatically attempt to stop any processes associated with Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that rkill is an infection, do not be concerned. This message is just a fake warning given by these Rogue programs when it terminates programs that may potentially remove it. If you run into these infections warnings that close Rkill, a trick is to leave the warning on the screen and then run Rkill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that rkill can terminate these Rogue Programs. So, please try running Rkill until malware is no longer running. You will then be able to proceed with the rest of the instructions.

Scan for Spyware/Adware

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

Please post the log from Malwarebytes when complete.

I've run rkill but when I click on any of the links to download Malwarebytes Anti-Malware the browser closes. I've downloaded Malwarebytes Anti-Malware on another computer on my network and saved it as zztoy.exe to a shared folder, but when I run it on the infected computer the installation closes after asking the language.

I'd like you to try going to the SuperAntispyware Online Safe Scan.

Follow the instructions as provided on the page to start the scan.

If you are unable to reach that page on your infected computer, you should be able to save the downloaded file to a thumb drive and take it to the infected machine and run it directly from there.

I would recommend disconnecting the infected computer from your network so we don't spread the infection any further than it is now.

Please post the results of the scan when complete.

I'm very sorry but the link I inserted was incorrect. I have updated the link and am also posting it here.

I have found the SuperAntispyware Online Safe Scan and was able to start it. But in the middle of the scan a blue screen appeared and the computer automatically restarted.

Let's dig a little deeper.

We need to run a GMER scan
  • Download GMER and save to your desktop. Note that the file will be randomly named to prevent active malware from stopping the download.
  • Close all other open programs as there is a slight chance your computer will crash.
  • Double click the GMER program. Your security programs may detect GMER's driver trying to load. Allow it.
  • You may see a warning saying "GMER has detected rootkit activity". If so, select NO.
  • Make sure all options are checked except:
    • Sections
    • IAT/EAT
    • Drives/Partition other than Systemdrive, which is typically C:\
    • Show All (This is important, so do not miss it.)

    Note: If GMER crashes or hangs, please retry running a scan. Only this time, in addition to the options mentioned above, uncheck Devices as well.

  • When the scan is complete, click Save and save the log onto your desktop.
Please post the log when complete.

If none of those utils will run, then your computer is going to require tools which are not permitted in this forum. At this point, I think this one is best left to the experts, so I'm going to refer you to the Virus, Trojan, Spyware, and Malware Removal Logs Forum.

Please read the Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help in cleaning your computer. Once complete, post a link back to this forum so the HJT team knows what we have tried.

Please be patient as the HJT team is quite busy sometimes and it may take a day or even a few for someone to pickup your log but someone will get back to you.

I have a malware in my computer. Techextreme tried to help me in this thread:
http://www.bleepingcomputer.com/forums/t/306163/need-help-with-a-virus/
but he couldn't remove it.
I was doing your preparation guide and downloaded DDS but my computer says it is an Autocad script and when I double-click on it, it opens in a notepad window.

Hello,

I have merged you new logless topic to your previous topic. Since you are unable to run DDS, please try 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 and we will provide you with additional instructions.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/306664/need-help-with-a-virus/ 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 MRT 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 MRT 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 MRT 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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

Orange Blossom :thumbsup:
