Hi.
Edit: I believe I may have put this in the wrong section. If I have, I apologize wholeheartedly.

I'm hoping to find some help here after a lot of googling in vain, this problem recently cropped up after installing a Cisco E2000 Router on our network.

On all devices on the network, including my Samsung Galaxy S (T-Mo Vibrant), 2 iPod Touches, 2 Laptops, and 1 Desktop, random web pages open while browsing, frequently while clicking on a link or opening a new tab.

They direct to google-analytics.com, which then turns into advertisements for various things. Nothing in particular. We run SuperAntiSpyware as well as Microsoft Security Essentials on every compatible device; various scans have shown no infected files or any problems.

I am e-mail subscribed to this thread already, so I will immediately respond to any help rendered :)

If there's any other information needed, please, let me know.

The computers on our network are all Windows 7, 2 Home Premium 64 1 Ultimate 64.

Thanks for your time
-Connor

Edit: Thanks, Animal, and I'm sorry I put it in the incorrect section

Sidenote: Downloaded MalwareBytes and did a full scan. No infections.

Appears you mau have a Bootkit infection. I see you have a 64 bit sytem some tools are restricted. Let's run one onloine scan.
Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.

And here is the log I pushed to a text file:

C:\Users\Estanzo\Downloads\ConvertXtoDVD 3.3.2.100.rar a variant of Win32/Keygen.AS application deleted - quarantined



The problem persists; while hitting "reply to this thread" a google-analytics.com page opened. Ironic.


Thanks for this and any continued help!
-Connor

Your welcome.. we will run MBMA and a boot scan. You used a Key generator and as is usually the case they infected your machine to steal personal info.


Next run MBAM (MalwareBytes):

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 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. 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.

Troubleshoot Malwarebytes' Anti-Malware


If this doesn't run we will have to do something else.

To check for and confirm the MBR rootkit,
Please download mbr.exe and save it to the root directory, usually C:\ <- (Important!).
  • Go to Start > Run and type: cmd.exe
  • press Ok.
  • At the command prompt type: c:\mbr.exe >>"C:\mbr.log"
  • press Enter.
  • The process is automatic...a black DOS window will open and quickly disappear. This is normal.
  • A log file named mbr.log will be created and saved to the root of the system drive (usually C:\).
  • Copy and paste the results of the mbr.log in your next reply.
If you have a problem using the command prompt, you can just double-click on mbr.exe to run the tool.

Yeah I was suspect that it would rin on a 64 so we need to do this.
Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.
