Bubnix-Avira cautions in Sys vol info

    I got a system crash a few weeks ago, can't remember if it was when dl a pdf/flash/java and after a reboot everything seemed normal. However Avira started to quarantine many dll's or sys files in system32 as virus, endlessly. I then rebooted once more, and no more Avira notifications, apart from every once in a while saying it found bubnix in System volume information.
    I want to be sure that it is fully removed.
    I'm suspicious of the tdrsa.sys file mentioned in the logs.

    Now please double-click the RootRepeal.exe previously downloaded.
    • Select File then Scan
    • On the Select Drives form select drive C by "ticking" the box for drive C and click OK
    • When the scan is complete - highlight each of the following file(s) (one at a time if more then one is listed) by left clicking it. Then use right mouse click and select the Wipe File option only for each file.
      • C:\WINDOWS\system32\drivers\tdrsa.sys
    • After Wiping all files, immediately reboot your pc!
    After reboot, continue with the below.


    Now we need to use ComboFix
    • 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.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    FileLook::
    C:\WINDOWS\system32\drivers\tdrsa.sys
    
    File::
    C:\WINDOWS\system32\drivers\tdrsa.sys
    c:\windows\system32\config\systemprofile\Application Data\vqdlkr.dat
    
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}]
    
    • 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

      http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif

    • 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.


    I strongly advise you to cleanup your Desktop. Remove eveything but links to run programs. Do not download and save programs here and defintely do not use it for long term storage.

    You need to keep ComboFix.exe here for now as we need it, but we will be removing it when we are finished with your cleanup. A cluttered Desktop is malware's playground and it can also cause performance degradation especially when you start saving large files here.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this.

    Now run Rootrepeal again as you did the very first time and attach the log it produces, as I go through your logs. I want to be sure it is not reporting the file's presence any more.

    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" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. 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.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of 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.
    10. After doing the above, you should work thru the below link:
