My girlfriend's computer seems to be infected with something. It is a Compaq computer with Window's Vista operating system. She went to a site which I believe was called Shopathome.com and downloaded a toolbar called SelectRebates 4.2. I didn't know it at the time, but her antivirus program (CA Internet Security Suite) started reporting it as a detected infection of type browser helper object, but did not - or could not - quarantine it.

When I found out about it, I tried uninstalling it with Programs and Features, but it gave an error message saying the uninstallation failed. I reran the Antivirus and it still reported an infected file, but did not quarantine it. I tried running Malwarebytes, and it reported no infections. I wanted to run both an antivirus scan and a Malwarebytes scan in Safe Mode, but I could not seem to get into Safe Mode. I found out on another website that I could run msconfig and get the computer to restart in Safe Mode that way. When I did I also looked at the startup programs and noticed that SelectRebates was listed there, and I unchecked it so it would not startup with the restart.

Malwarebytes again found no infections, and the Antivirus program detected SelectRebates, but did not quarantine it. At this point, I decided to try going back to normal mode and try running both programs again with SelectRebates not started on startup. This time Malwarebytes found a trojan - gensysrep[1].exe and quarantined it, and the antivirus seemed to be running, but it ran very quickly and seemed to be operating differently. This time it reported that there were no infections found. This did not seem to be right, so I decided to check with you to see if there was a problem.

I ran DDS, and will attach the logs, as well as the Malwarebytes log. I tried running GMER, but it seemed to go for a while, and had some information on the screen, but when I tried to save the information, the computer got hung up somehow on the save operation, and I had to turn off the computer by the power switch in order to get out of it. I decided to send you the information I have and find out what to do next. {Edit: While I was waiting for an answer, I tried some things to get GMER to run that I found in another Bleeping Computer post, and got a result by unchecking devices and sections before running GMER. I have now attached ark.txt.}

By the way, the Antivirus program found the files in the registry at the locations: HKLM\software\shopathome and HKLM\software\shopathome\SelectRebates.

Thank you for responding to my post.

Here is a little more information. We have 2 computers in our home, my girlfriends' is connected to the internet by a wireless connection to a router. Mine is connected to the internet by hardwire to the same router. There is a firewall built in to the router that should be active, unless it was somehow hijacked. We both use the same security software, CA Internet Security Suite 2010 which has has Antivirus, Antispyware, Antimalware and firewall capabilities. These are all enabled and are setup to act in realtime, and are also setup for automatic weekly full scans. I also have Malwarebytes on both computers that I use as a secondary on demand scanner only.

I believe that I may have an infection of some sort on my computer as well, but am going to try to cure her problem first. My intent is to try to keep her computer disconnected from the internet while working on these problems, so I will not risk any malware hiding out in the other computer, and then reinfecting us later. Please let me know if this is necessary or not. If so, I will be be transferring information to and from her computer via flash drive. I am not sure if this problem spread from her computer to mine, or if we just happened to get simultaneous infections through different sources. This brings up a few questions. Will you be able to work on my computer's infection as well as hers, or should I start a separate thread? Also, if I need to use a separate thread, can I work on them at the same time (if that is even possible with a 6 day wait time) or should I wait to get one cured before starting on the other?

Again, thank you in advance for your help.

Transferring via flash drive is fine, so ignore the instructions when they say download to the desktop and transfer them to the desktop via the drive. You are right to keep these connections shut until we know what's happening.

The probable route was one PC to another. I will deal with your girlfriend's machine first and then straight after we'll look at yours. Don't try and use her fixes on your machine as this will probably not help.


First, let's run a specific rootkit search

  • Download TDSSKiller and save it to your Desktop.

  • Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.

  • Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l report.txt

  • Now click Start Scan.
  • If Malicious objects are found, ensure Cure is selected then click Continue > Reboot now.
  • Click Close
  • Finally press Report and copy and paste the contents into your next reply. If you've rebooted then the log will be found at C:\

Do I need to do anything to keep the flash drive from infecting the other computer if it is not already infected?

Keep the infected machine disconnected from the internet but otherwise the flashdrive isn't easily infected when transferring files to the PC's removable device drive. We can always check the flashdrive afterwards.

Can you now run MBAM and SAS

Please download Posted Image 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 or, if you are using Vista, right-click and select Run As Administrator 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 MBAM won't update then download and update MBAM on a clean computer then save the rules.ref folder to a memory stick. This file is found here: 'C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware' then transfer it across to the infected computer.
  • On the Scanner tab:
    • Make sure the "Perform Full 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 you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.


And

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • 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.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • 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.

We were going to stay off of the internet. Do you want me to reconnect to the internet to update these before running?

Edit:Sorry, I read a little closer after I sent this and saw that you can copy the files over on the flash drive. I will send the reports after running the scans.

Both scans completed. Malwarebytes found no infections, I didn't reboot after it finished, because I missed the part on your post that said to reboot regardless if it asked or not. I hope that is not a problem, but it did not find anything anyway.

SuperAntispyware found 48 items and I followed the directions and removed them all and then rebooted. I noticed that approx half of them were related to ShopatHome and SelectRebates.

By the way, I had a difficult time tracking down the rules.ref files on both computers because one is Window's XP and the other is Window's Vista and the application data are stored in different locations. Also, I believe I had to enable showing hidden files on both computers in order to find the correct locations. You may want to include that in your instructions in future. Also, the link that you gave to download the SAS definition files did not have a download installer hyperlink, but I was able to find it by clicking on the Click here for information link under Definition Database. Edit:I tried putting a link to the page where I found the definition file in this post, but when I tried to click on the link I put in, it sent me to the same page that your link sent me to. I'm not sure why that happened.

I will be going to bed after posting this as it is after midnight here, so I will check for your response tomorrow morning. The logs are posted below:

Let's run ESET to see if we can find the origin of this adware

  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Leave the top box checked and then check Posted Image
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
  • Push Posted Image
NOTE: If no malware is found then no log will be produced. Let me know if this is the case.

Apparently ESET has changed their webpage, and their online scanner. The free Online Scanner button was not on the page that your link sent me to. I had to click on a link at the bottom of the page to get to the page with the button on it. It is also now able to be used with other browsers, and I could not find a way to download esetsmartinstaller_enu.exe and transfer it to the other computer, without installing it and immediately running the scan online. Should I go back online with the other computer in order to run this? If not, what is the alternative?

That link sent me directly to the page that had the free ESET Online Scanner button. But, remember, I was staying offline with my girlfriend's computer. I clicked on the link with my computer, which I believe also may have some kind of problem. I was trying to get a file that I could transfer to her computer via memory stick. Should I go back online with her computer and run ESET scanner? Edit: I just tried the original link again, and this time it sent me to the page with the button on it also. Don't know what happened the other day.
