a work pc started not to be able to run executables except for microsoft security essentials and IE explorere. Since yesterday, the pc will still allow explorer to be started but it says there is no internet access.
When I run security essentials I get this message:

The message on the security essentials is:Rootkit:Alureon_>Mbr::Alureon
* now has no network access
* says to remove I must reboot which I did (a few times) and the same issue is there.
* the only program that starts is explorer but as there is no
* when it is almost up it gives a message about having a
compatibility issue with Microsoft small business server.

have tried to run anti virus programs from a usb stick but it will not allow them to start.

HELLLLLP!

Hello and welcome,I moved this from WIN7 to Am I Infected.

Reboot into Safe Mode with Networking
How to start Windows 7 in Safe Mode


This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes 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 and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 and continue.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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 the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

-- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, go to Start > All Programs > Malwarebytes Anti-Malware folder > Tools > click on Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).

Ok, 2 more tries before we go shaman...
Try doing a System Restore to a date before this all started,then do post 2.
OR

Login as the Administrator user. For Windows 7 or Windows Vista, you will be prompted to enter your Administrator account password.

Once you enter the password, your browser will start and you can download the above FixNCR.reg file. When saving it, make sure you save it to a folder that can be accessed by your normal account. Remember, that you will be launching the browser as another user, so if you save it to a My Documents folder, it will not be your normal My Documents folder that it is downloaded into. Instead it will be the My Documents folder that belongs to the user you ran the browser as. Once the download has finished, close your browser and find the FixNCR.reg file that you downloaded. Now double-click on it and allow the data to be merged. You should now be able to run your normal executable programs and can proceed to the next step.

I gave it to the shaman and he worked on it for over 8 hours and finally decided to reinstall. this is one nasty bug. from what he is telling me it creates it own partition and you can not see it. virus creaters are scum bags.

he brought it back today. he thinks that the virus actually goes out in to the dell recovery section of the hard drive that nobody can see. he did numerous restore points and the virus was still there. apparently there has been a lot of folks fighting this bug.
