Hello. I have encountered a problem with my PC.

In Google and other search related websites, whenever I run a search, i'll click on a link and it will redirect me to another page.

It appears to only be affecting search websites.

I'd really appreciate some help with resolving this issue. :thumbsup:

Hi rgallos and :thumbsup: to Bleeping Computer!

MALWAREBYTES ANTIMALWARE
-------------------------------------------
Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM 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.
  • 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.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to myscan.exe.
  • Double-click on myscan.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

regards, Elise

Still getting the redirects?

If you do have windows XP, you really should update to service pack 3 to keep your computer safe. I recommend to turn on automatic updates and install all express updates.

ATF-CLEANER
------------------
Please download ATF Cleaner by Atribune. (This program is for XP and Windows 2000 only)Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.
If you use Firefox browserClick Firefox at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.
If you use Opera browserClick Opera at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.
For Technical Support, double-click the e-mail address located at the bottom of each menu.


ROOTREPEAL
-------------
We need to check for rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive.
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

regards, Elise

Yeah, it's still redirecting.

Thanks for the advice, I'll install Service Pack 3 as soon as we're able to hopefully fix this problem.


I ran both ATF Cleaner and Rootrepeal.

Here's the Rootrepeal log:

Okay, no rootkits there.

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.

    • 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.

regards, Elise

I've done everything, but can't boot up the computer in Safe Mode.


It takes me to the screen and I click Safe Mode, but the computer just keeps restarting and entering this screen, but it doesn't seem to be able to log in in Safe Mode.

Okay, thats not what we want.

Reboot your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option Disable Restart on System Failure.
Now try to boot in safe mode. It should give you a BSOD (a blue screen with a message that your system crashed). Please give me the text of that BSOD in your next reply.

regards, Elise

I don't know if there's something wrong with the computer or if it's just me not doing everything as it should.

I rebooted the computer, tapped F8 and selected Disable Restart on System Failure.

After that; however, the computer goes directly into the Windows icon screen and logs in and I don't get a chance to boot up the computer in Safe Mode.

Sorry, I should have explained it. That option will cause your computer not to reboot when it crashes. This will give you the opportunity to see the error message.

After choosing this option it will boot normally. Just reboot, tap F8 and now choose safe mode.

regards, Elise

Sorry elise, but I can't seem to get the blue screen.

After I do what you told me, all I get is a screen that leaves this message:

"We apologize for the inconvenience but Windows did not start successfully. A recent hardware or software change might have caused this.

If you computer stopped responding, restarted unexpectedley or was automatically shut down to protect your files and folders, choose last known good configuration to revert to the most recent settings that worked.

If a previous startup attempt was interrupted due to a power failure or because the power or reste button was pressed or if you aren't sure hwat caused the problem choose start Windows normally."

Then it gives me the option to Start in Safe Mode or Start Windows Normally or Last Known Configuration, but it never gives me a blue screen.

Well, I don't think you have a lot of options here, I think these problems are caused by the malware.

The only way I see to get rid of the virus (except a reformat) is something like Dr. Web Live CD

The link describes pretty clear what you will have to do in order get the scan working. If you have any more questions, please let me know!
