    First off, I have Windows XP with SP3 and BitDefender as an antivirus.

    Anyway, I'm not sure when it started, but it was at least a few weeks ago. All of a sudden my computer got infected with a bunch of viruses/trojans. I'm pretty sure I got rid of all of the viruses/trojans but I'm not sure. Anyway, I dont know if it has anything to do with it, but ever since then on startup this folder (mentioned in title) C:\Program Files\Common with two "helper" files in it keeps popping up. It's really irritating me! I followed the "READ & RUN ME FIRST" and in the process some of the scanners deleted the two helper files (helper.dll and helper.sig) but the Common folder still opens on startup!

    How do i get rid of this??

    I'll attach the logs to the scans.

    more of the logs.

    I've attached logs from both when my computer got seriously infected and from when I went through the whole "read and run me first" post yesterday.

    Welcome to Major Geeks!

    You did not use the current versions of SUPERAntiSpyware and Malwarebytes. So just to be safe, let's get them installed. Also you did not attach the log from MGtools that we need to continue.

    • Please uninstall your current version (this is necessary).
    • Then download this SUPERAntiSpyware
    • Install this new version. It may tell you that you need to reboot to complete the installation. You must reboot at this time.
    • After the reboot, run SUPERAntiSpyware and immediately click the Check for Updates button to get more updates for the database.
    • Now run a new full scan of your system. And attach this new log.
    Now run Malwarebytes and click the Update tab. Then click the Check for Updates button so you update to the current version of the program and database. Then run a new scan with it too. Attach the new log.
    Now run MGtools as rquested in the READ & RUN ME and attach the MGlogs.zip file.

    Now we need to use ComboFix again.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below
    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.

    Also delete all files and subfolders in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\Temp
    C:\Documents and Settings\Alexandra\Local Settings\Temp

    Now run Ccleaner!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    When I ran ComboFix it deleted the "C:\Program Files\Common" folder so it didn't pop up when the computer was restarted. (Was that all that needed to be done?)
    Do you have any idea what that folder and those files do anyway? Seems like I'm not the only one who's gotten this problem before.

    Thank you very much for your help. :)
    Does my computer look clean?

    No that was just part of the remaining things to fix.


    It attempts to steal banking information. You can read about it in the below link: InfoStealer.Banker.D

    Your logs are clean.


    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
      • Delete the C:\combofix folder from combofix (if it exists)
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:

    So I'm done? It's safe to uninstall things now? (That's what it looks like)

    Thank you SO much! This was bothering me for weeks!
