    Physically disconnect from the internet.
    Boot from OTLPE and replace all atapi.sys files with my file.
  2. lizmcreations Newcomer, in training Posts: 60

    OK, unplugged my router AND booted to OTLPE (the first time I tried to replace all 6 files I had booted to OTLPE but didn't unplug my router) ....

    Still can't replace 2 of the atapi.sys files ...

    they are located in:
    windows\winsxs\x86_mshdc.inf_31bf3856ad364e35_6.0.6002.1805_none_df23a1261eab99e8

    and
    windows\winsxs\x86_mshdc.inf_31bf3856ad364e35_6.0.6001.18000_none_dd38281a2189ce9c

    It says the file is in use and cannot be renamed and then therefore the new file can't be put in its place.

    Could those two files be the ones causing the problems? I don't recall them even showing up in any of the other scans.

    I doubt, but let's try another way to replace them.
    Keep the computer disconnected from the internet.
    Restart computer in Safe Mode.

    Using OTM...

    • Please double-click OTM to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
    • Copy the lines in the codebox below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose Copy):

    Code:
    :Processes
    
    :Services
          
    :Reg
    
    :Files
    C:\Windows\winsxs\x86_mshdc.inf_31bf3856ad364e35_6.0.6002.18005_none_df23a1261eab99e8\atapi.sys|C:\atapi.sys /replace
    C:\Windows\winsxs\x86_mshdc.inf_31bf3856ad364e35_6.0.6002.18005_none_df23a1261eab99e8\atapi.sys|C:\atapi.sys /replace
    
    
    :Commands
    [purity]
    [emptytemp]
    [Reboot]
    
    • Return to OTM, right click in the "Paste Instructions for Items to be Moved" window (under the yellow bar) and choose Paste.
    • Click the red Moveit! button.
    • Copy everything in the Results window (under the green bar) to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy), and paste it in your next reply.
    • Close OTM and reboot your PC.
    Note: If a file or folder cannot be moved immediately you may be asked to reboot the machine to finish the move process. If you are asked to reboot the machine choose Yes. In this case, after the reboot, open Notepad (Start->All Programs->Accessories->Notepad), click File->Open, in the File Name box enter *.log and press the Enter key, navigate to the C:\_OTMoveIt\MovedFiles folder, and open the newest .log file present, and copy/paste the contents of that document back here in your next post.

    Ok, here are the contents of the log... can't tell if it replaced them or not, but I'm still having the redirect problem. Any other thoughts or suggestions?

    Delete your TDSSKiller file and download fresh one.
    Run it and post fresh log.
  6. lizmcreations Newcomer, in training Posts: 60

    OK, new log (no change in status - although I notice the log shows usbstor.sys "verdict 1" which I'm assuming means that file is infected as well? Should that driver be replaced too?)

    Download and save HelpAsst_mebroot_fix.exe to your desktop.
    • Close all open programs.
    • Double click HelpAsst_mebroot_fix.exe to run it.
    • Pay attention to the running tool.
    • If the tool detects mbr infection, please allow it to run mbr -f and shutdown your computer. To do so, type Y and press Enter.
    • After restart, wait 5 minutes, then go Start>Run, copy and paste the following command in the run box then hit Enter:

      • helpasst -mbrt
    • When it completes, a log will open.
    • Please post the contents of that log.

    IMPORTANT!
    If the tool does NOT detect any mbr infection and completes, proceed with the following...

    • Click Start>Run and copy and paste the following command, then hit Enter:

      • mbr -f
    • Repeat the above step one more time
    • Now shut down the computer (do not restart, but shut it down), wait 5 minutes then start it back up.
    • Wait another 5 minutes, then click Start>Run and copy and paste the following command, then hit Enter.

      • helpasst -mbrt
    • When it completes, a log will open.
    • Please post the contents of that log.

    **Important note to Dell users - fixing the mbr may prevent access the the Dell Restore Utility, which allows you to press a key on startup and revert your computer to a factory delivered state. There are a couple of known fixes for said condition, though the methods are somewhat advanced. If you are unwilling to take such a risk, you should not allow the tool to execute mbr -f nor execute the command manually, and you will either need to restore your computer to a factory state or allow your computer to remain having an infected mbr (the latter not recommended).

    I'd like to see something.
    Please, run fresh OTL scan.



    * Double click on OTL icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    * Under the Custom Scan box paste this in:


    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll

    IdeChnDr.sys
    viasraid.sys
    AGP440.sys
    vaxscsi.sys
    nvatabus.sys
    viamraid.sys
    nvata.sys
    nvgts.sys
    iastorv.sys
    ViPrt.sys
    eNetHook.dll

    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\System32\config\*.sav
    CREATERESTOREPOINT


    * Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.

    What happened to my atapi.sys in C:\ directory?
  12. lizmcreations Newcomer, in training Posts: 60

    sorry, the second time I tried to replace all the atapi.sys files I put your file on my usb thumb drive rather than on the c: drive ... I deleted it after the OTM.exe file move ... didn't even think about it, I was just thinking I would download it again "fresh" if I needed it again ... or use the one I kept on my thumb drive just in case somehow just being on the c: drive was causing the file to get infected or something ....

    Probably doesn't make any sense, but I'm just trying to do whatever I can to get the computer back to functioning :) and I appreciate all the help you're providing me.

    Liz
  13. Broni Malware Annihilator Posts: 39,324   +175

    No big deal :)
    We're both little bit frustrated...hmmmm...

    You still have my zipped file on your desktop.
    Please, unzip it, copy and paste atapi.sys into C:\ directory.
    Then, re-run OTL, using instructions from my reply #69.
    I need the scan to see that file so I can compare hash numbers (MD5).
  14. Broni Malware Annihilator Posts: 39,324   +175

    Yeah, it looks like we're dealing with the newest version of TDSS rootkit.
    I just found out more about it today.
    There are some test fixes ready, so hopefully we can do something about it.

    In addition to my previous instructions...

    Delete any GMER file, if you have one.

    Download GMER: http://www.gmer.net/files.php, by clicking on Download EXE button.
    Alternative downloads:
    - http://majorgeeks.com/GMER_d5198.html
    - http://www.softpedia.com/get/Interne...ers/GMER.shtml
    Double click on downloaded .exe file, select Rootkit tab and click the Scan button.
    When scan is completed, click Save button, and save the results as gmer.log
    Warning ! Please, do not select the "Show all" checkbox during the scan.
    Post the log.

    I'll be back here tomorrow evening (PST)
  15. lizmcreations Newcomer, in training Posts: 60

    Alright, I am not sure what is going on ... but I've run OTL.exe several times (deleted the .exe file and then re-downloaded it again) and I CANNOT get the extras.txt file! I didn't change any settings and I didn't pay enough attention to the settings when I did get the extras.txt file to notice if there was any difference. I have shut down and restarted and run it to try to get the extras.txt file and I can't seem to get it.

    But, attached is otl.txt.

    Will follow the next instructions shortly.

    I downloaded a brand new gmer and I still can't get it to finish running ... always has a problem and stops working and then the windows "this program has stopped working..." window pops-up.

    I downloaded gmer.exe from a different site to see if I could get it to finish ... still no go. But, this time I noticed that the status on the bottom (in case it makes a difference or tells you something)...

    It was scanning:
    \Device\HarddiskVolumeShadowCopy2

    Like I said, that might mean nothing .. but it might also tell you why the program (gmer.exe) is failing.

    I just got home, so I'll be slow with replying (tons of other topics).

    If we're dealing with this new type of TDSS rootkit ( and it looks like we do), we'll have to make GMER running. As of now, it's the only tool, which actually detects this new type of TDSS.

    Run rKill first.
    When you start GMER, UN-check "Devices" in right pane and try to run it.

    If still a problem, restart in Safe Mode and try from there.

    From OTL log I can see, that the infection is still there.
    Don't worry about Extras. It's not important at all at this moment.

    ok, ran rkill and then gmer without the "devices" checked ... got farther in the process but I got the "blue screen of death" while it was searching files. So I booted back-up in safe mode and re-ran gmer. Has run fine so far, still running for just aout 12 hours at this point. Just giving a quick update in case you login ... I will post the log as soon as it stops running, which I think will be soon.

    Thanks,
