I've got a Windows domain with multiple workstations on it. On all workstations connected to the domain, when browsing to certain sites, the site loads correctly, and then is redirected to a generic search site that appears to host malware. The behavior is the same with Internet Explorer and Firefox. On a laptop connected to the domain, I removed it from the domain, and connected to the internet using wifi tethering on my smart phone. When I did that, the sites loaded correctly. I also changed the DNS server on one of the workstations to Google's, and that did nothing to help the problem.

These are the sites that are currently loading wrong, and what they redirect to:

hxxp://www.adesa.com redirects to hxxp://pagesinxt.com/?dn=adesa&fp=%2BRIDj92nHboPlDTfOH3sjRbf8LP6RL3DYagTd0vQ8dmCaNYpM8d2HjM7ybVb3fHyW7K8ARmdAqJ1rtOKBGWQiw%3D%3D&prvtof=Uaw6cCdQfTBtNAthkkQJnDa2Onpqg%2F0M92UYJQgE5F5HiGGly1nxCPE0pW4%2Bb0ox&poru=K%2FpJewA3eHBYz1OdwL1o30hjzT1qeiLOyv7%2B%2FXGmatKJofwvTAiuLODdXxad1iEF5eopjlIefVND3YGYkDdwEq6Vsq3McovEhFDVWYNZbIk%3D&cifr=1&flrdr=yes&nxte=js

hxxp://www.priorityclub.com redirects to hxxp://pagesinxt.com/?dn=cls.ichotelsgroup.com&fp=zWyT5wBXmcQWHfrEcI%2BDjfoC%2Bbkh3eyA9Qi2zHSCZq0j7oBQqdeA0OdNUsWnq91NuDpOPFa85ikXkDhFw0Aaug%3D%3D&prvtof=LxmEj0vXdAyJDuApoWkDkatCeePeNVz6fsrpN5ondYQBvGCEW8Un1vjVCQjP1hvascWJGrYjCShGweVmfs0SVg%3D%3D&poru=8qtpZ9370vX7els2ZD47ni6AjG17gaNbWTMtX9sncaAweVQsO%2BDDkwwJcCtcTeXqdKyUSl8byJsVNI7RuWoAMZ9GHP4WmMJILvA%2B%2FrZlcaY%3D&cifr=1&flrdr=yes&nxte=js

The only similar incidents that I can find relating to the pagesinxt.com domain forcing redirects is on blog and igoogle pages that have a 3rd party widget on them causing the redirect, this doesn't apply to our situation.

Has anyone had any experience with something like this? A virus scan on the domain controller comes back clean.

Any ideas would be greatly appreciated.

Please run these on a few computers and post the resulting logs with edits to hide company / domain information.

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Please download and run Security Check from HERE, and save it to your Desktop.

* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt; please post the contents of that document.

Malwarebytes Anti-Malware

NOTEMalwarebytes is now offering a free trial of their program, if you want to accept it you will need to enter some billing information, so that at the end of the trial you would be charged the cost of the product. Please decline this offer, if you are unable to provide billing information. If you want to try it out, then provide the billing information.

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.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 it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • 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 "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are unchecked (leave all others checked):
    • Ignore files larger then 4mb
    • Ignore non-executable files

    Now Perform the scan with SUPERAntiSpyware as follows:
    • Launch the program and 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 and click "Next".
    • 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" and reboot normally.
    • To retrieve the removal information after reboot, launch SUPERAntispyware again.[list]
    • 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.

SAS Portable
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.


All scans above should be performed in regular boot mode, and if that is not possible then I will post instructions in a follow up reply on how to get into Safe Mode to perform the scans. Also all scans should be COMPLETE and not quick unless specifically instructed to do so.

GMER - This is a 64bit system, so I don't know if it ran correctly due to the note saying that it won't run in 64 bit mode. It appeared to run, and notified me that it had found no system modifications, but the log was completely blank.
