Yesterday, my dad seems to have picked up a virus of some sort that has quickly rendered our Norton Antivirus useless, blocks access to websites such as www.norton.com, the support page for Microsoft and multiple other useful links. Also, when clicking on a search result in Google, he gets redirected to other, lesser known search engines of some sort. The last symptom that was have noticed is the computer running very slowly. It takes ten or more seconds to right click.

The computer is currently running on Windows XP Professional. Also, something to note is that the same morning, we encountered a virus called prunnet.exe. We promptly removed it and everything associated with it by following the steps on the third post titled "removal of prunnet.exe" at http://forums.cnet.com/5208-6122_102-0.htm...ssageID=2916950. I believe that doing those actions has removed that particular malicious file, but we think that this more recent virus is another all together as it seems to have some different symptoms than prunnet.exe. We currently have the computer off and unplugged from the internet.

Does anybody here have any idea what this could be? Do you think it is associated with prunnet.exe? Thank you for your help.

Also, the not being able to access certain pages and Google links being redirected happens on both IE and Firefox.

Let's start with a Malwarebytes log.

Please download 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.
  • 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.

-- 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.
