AproposO trojan

    I got a message from Norton's that I have a trojan in my C:\windows\temp\~aproposO\ph.exe file. I ran all the spyware programs in the tutorial and I am clean. When I try to delete the file (in normal and safe mode) I get the message about the file being protected or in use. I also did eveything that Nortons website said to do but the file is still there. Any help would be appreciated. Thanks, Mariah

    Mariah,

    If you have completed all the steps of the READ ME FIRST, follow the guidelines below and post your HJT log.

    Make sure you have HijackThis 1.99 and follow the guidelines on where to install it and how to post a log as an attachment. This is all covered in the sticky thread NO HIJACK THIS LOG FILES BEFORE READING THIS: HJT Tutorial & LOG File Posting

    Now post a HijackThis log as an attachment to your message (Do not post the log inline). All running programs should be closed, including your web browser, e-mail. Close before running Hijack This!

    To repeat: Do NOT run Hijack This from the Desktop, a temp folder, or a sub-folder of C:\Documents and Settings, or choose to run it directly from the downloaded ZIP file. Place it in its own folder, for example C:\Program Files\HJT

    The only line in your HJT file that needs to be fixed is below.

    Run HijackThis and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    O23 - Service: Content Monitoring Tool - Unknown - C:\WINDOWS\system32\msCMTSrvc.exe (file missing)


    After clicking Fix, exit HJT.


    Is this the full actual path to the problem file.

    C:\windows\temp\~aproposO\ph.exe

    Assuming the answer is yes, download Pocket KillBox from http://www.downloads.subratam.org/KillBox.zip

    Extract PocketKillbox to its own folder and run it. Select the option to Delete on Reboot.

    1) Now, Copy and Paste C:\windows\temp\~aproposO\ph.exe into the box
    2) Now, Click the Red X and Yes to the confirmation message.
    3) A message will ask if you want to reboot now – Click yes.

    Allow Pocket KillBox to Reboot your computer.

    After reboot check to see that the file is actually gone. You may want to now delete the folder yourself:
    C:\windows\temp\~aproposO

    Ran HJT and fixed the file (it is gone)
    Ran KillBox and when I paste in the aproposO file I get the message that this file does not seem to exist....I tried browsing for the file with the KillBox program in order to enter the file and I get the message that I can't
    access the file. When I try to reboot my system I get the message that SMART Hard drive detects imminent failure...Attribute failed: 05

    Thank you for your help. Mariah

    Actually all we did was remove an entry in the registry to load a file that was already missing.




    Nothing we were doing has anything to do with this error message. Sounds like you have a hardware problem.

    Does Norton still detect that C:\windows\temp\~aproposO\ph.exe?
    It's strange you said you could see it before but now killbox cannot find it. That would mean it is already gone. So who deleted it.

    mariah Private E-2

    Yes, I just got another alert from Nortons that I have a download.trojan that Nortons is unable to repair. It gives me C:\windows\temp\~aproposO\ph.exe as the object name. I can find the folder which is empty and when I try to delete that folder I get the message that the folder cannot be deleted and access is denied. KillBox cannot find that folder when I paste it in....but when I use the feature on Killbox that lets you browse to find the file, I can find it but cannot access it. Perhaps I am doing something wrong? Thanks for sticking with me. Mariah

    Are you sure you have enabled viewing of hidden files?

    When you do the below, exactly what happens? Make sure you use copy and paste!

     
  9. mariah

    mariah Private E-2

    I have enabled viewing of hidden files. When I click yes that I want Killbox to reboot I get this message: PendingFileRename Operation Registry Data has been removed by external process! I am apparently having some hardware problems because when I restart my computer I get the message I told you about earlier about immiment failure of my hard drive and I have to press F1 to boot and that bypasses my regular login...it goes right to my desktop. This all started with Norton telling me I had a trojan. I probably did something wrong when I was trying to get rid of the virus before I checked with you. I am wondering if Killbox isn't working because it can't reboot my computer? Mariah
     
  10. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    The problem with Killbox has not related to your hardware problem. There are sometimes things running (including malware) that removes the instructions to delete on reboot from the Pending Operation list in the registry. That is what the message you are getting means.

    Try this: use Killbox again and after clicking the Red X and Yes to the confirmation message, do not continue on to the next message that asks about reboot. Do the following (it's a sort of drastic measure). At this point, physically unplug the power cable into your PC. We do not want a gracefull shut down which could erase the pending operation info again.

    Now wait a minute and them power back up. And see if we got the file deleted or not.

    You should be more concerned about the possible failure of your hard disk. You should note the EXACT word for word message you get and paste that into a thread in the Hardware Forum.
     
  11. mariah

    mariah Private E-2

    I did the "ungraceful" shutdown and the file is still there. I get the following message when I try to delete it:
    Error deleting file or folder:
    Cannot delete ~aproposO access is denied
    Make sure the disk is not full or write-protected and that the file is not currently in use. I will post a thread in the hardware strand concerning the imminent hard drive failure. I have never had to experience a hard drive crash and it is not on my life list. :) Mariah

    Does the below link sound like your problem:

    http://www.theglobeandmail.com/servlet/story/RTGAM.20021223.gts3/BNPrint/Technology/

    If so, sounds like it is time to get a new one before you lose all your data.

    The below may be a waste of time if your hard disk is on the verge of crashing but if you do buy a new one and perform an image copy, you will still need to be able to remove this file later). But it's up to you if you want to keep trying. I would look in the sale papers from last weekend and get a hard disk unless you are still under warranty.

    I also want you to do two other things for me related to figuring out why we cannot delete that folder:

    1) Generate a StartupList log using HijackThis
    Run HJT and on the first screen, click the button that says "Open the Misc Tools section". In the next window first select "List also minor sections (full)" and then click the button that says "Generate StartupList log". CLick Yes to the Do you want to continue prompt. Now a notepad window will come up with the Startuplist.txt file. It is already saved in the the directory HJT is running from. So just come back here and upload the file as an attachment to your next message.

    2) Download ProcessExplorer from: http://www.sysinternals.com/files/procexpnt.zip
    Unzip it and now run ProcessExplorer and lets configure some options first:
    Click View and select Show Lower Pane. And where it says "Lower Pane View" make sure DLL's is checked. Now click on explorer.exe. Now also under the View menu choose "Select columns" and put a check mark on "Image Path".
    Now click on File and then Save As. And save the process list. Post it back here as an attachment. You can use ProcessExplorer instead of Task Manager. Sometimes ProcessExplorer can show and kill things that Task Manager cannot.


    Also a question: do you have an original WinXP bootable CD.

    Yes, unfortunately the link you gave me sounds just like the hardware problem I am having.

    I have attached the two files that you requested. I have not found the original WinXP CD but I am sure I can find it.

    Thanks,

    I don't see anything in those logs that would indicate a problem. See if you can locate your WinXP disk. I thinking about booting to the recovery console and then trying to delete the file.

    Sorry I have taken so long to respond to your last reply. Unfortunately, I do not have an original WinXP bootable CD. I am still getting a message from Nortons that I have an AproposO trojan. The message comes up after I run Ad aware. The file is still on my C drive along with another suspicious file called AutoUpdateO. Both are not deleteable. I am not having any problems like pop ups or hijacked home page or even slow computer. I wouldn't know I had this "nasty" if Nortons didn't give me a message. Sure wish I could delete the AproposO file. Thanks for all your help.

    I searched the registry and found nothing for ph.exe. I followed the directions for using regedit given at the link you gave me but not being a " Major Geek" I could have possibly done something wrong. I searched .exe just to see if anything turned up and of course lots of files did but no ph.exe. Thanks again, Mariah

    When I place the pointer on the folder it says it is empty. When I try to open the folder by clicking on it, I get a message that the file is not accessible and access is denied. I have two other folders in the temp file that deny me access. I have enabled viewing of hidden files. Thanks, Mariah

    Try downloading and using this ExplorerXP to look at those folders. Does it should anything?

    Also try this:

    Open a command prompt by clicking Start, Run, and enter cmd and click OK.
    Now in the command prompt window enter the following lines each followed by the enter key (at any prompts you get just answer yes! Make sure you enter the commands correctly, don't miss the spaces):

    C:\windows\System32\cacls.exe C:\windows\temp\~aproposO /g Everyone:f
    cd C:\windows\temp
    attrib -r -h -s *.*
    dir /s > c:\filelist.txt
    exit

    See if you can delete that folder now.
    Then come back here and attach that filelist.txt file which is in the root folder of drive C.

    I downloaded ExplorerXP and I was able to open the file....I saw files for updating and installing and uninstalling along with files with numbers...I was excited to be able to open the files. I tried to delete them and was able to. However, when I tried to empty the trash, the files are not deletable and I cannot open them or restore them. They are sitting in the trash. When I run cmd the files cannot be found. When I try to upload the filelist you requested, it cannot upload because the file is too large. Which means I probably did something wrong. I fear I jumped the gun by trying to delete the files before I ran cmd . You did not tell me to do that. :( Mariah
     
  22. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Put the filelist.txt into a ZIP file and upload the ZIP file.

    What were some of he filenames you saw?

    Please download the below tools but only run what I specify:

    Pocket KillBox

    VX2.BetterInternet Finder XP/2k - Version Msg126

    Generic Find It Tool - NT/2000/XP


    Extract all the files from the Generic Tool into its own folder.
    Then run find.bat. Post the log it creates back here as an attachment.

    Unfortunately, I did not write down the names of the files but I remember that they were something like downloader, auto update and some just had numbers and letters. They are still in my trash but I cannot open them.

    I have uploaded the files you requested. Thanks for your persistence.

    Well it look like you did not go to the correct directory from the command prompt like I asked. You were supposed to be in c:\windows\temp when you executed the dir command. You were still in C:\Documents and Settings\Pam. So the file did not give me what I was looking for. However, something I saw in there (on a brief glance) is the following and I would lay odds that they are bad:

    Directory of C:\Documents and Settings\Pam\Application Data\creativefork

    7 File(s) 1,587,046 bytes

    Do you recognize this folder and these files? They all strike me to be rather typical of malware files!

    mariah Private E-2

    The files you listed are nothing I recognize.

    Whenever you ask me to give you info or perform tasks I usually have no idea what I'm doing so it is with great fear and anguish that I await your replies...guess I messed up. I know I am suppose to have some knowledge of computers but I fear I am way out of my league with this list serv. Thanks for not getting too frustrated with me.

    Mariah,

    Don't worry about how complicated it appears! We will get there eventually and you will learn a bunch on the way.

    See if you can locate the below files mentioned in my last message. They are all in the C:\Documents and Settings\Pam\Application Data\creativefork folder.
    10/24/2004 08:11 PM 302,902 afoavayh.exe

    I want you to rename each one by right clicking on them and select rename. Then for each one just change the .exe extension to .bad

    The go back and do the below again and make sure your command prompt indicates that you are in the C:\windows\temp folder before doing the attrib and dir commands. If you have a problem doing this or do not understand something. Just tell me.

    Open a command prompt by clicking Start, Run, and enter cmd and click OK.
    Now in the command prompt window enter the following lines each followed by the enter key (at any prompts you get just answer yes! Make sure you enter the commands correctly, don't miss the spaces):

    C:\windows\System32\cacls.exe C:\windows\temp\~aproposO /g Everyone:f
    cd C:\windows\temp
    attrib -r -h -s *.*
    dir /s > c:\filelist2.txt
    exit

    See if you can delete that folder now.
    Then come back here and attach that filelist2.txt file which is in the root folder of drive C.

    I have renamed each file but how do I get into the C:\windows\temp folder from the command prompt window? Mariah
     
  28. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    That was in my last message and an earlier one!

    cd C:\windows\temp


    cd - means change directory which is what folders were originally called in older OS's. The words are used interchangeably now.

    Dr. C,
    I ran the cmd..when I typed the first line I got the message that the file couldn't be found. I tried several times to make sure I wasn't doing something wrong. I typed the second line and got into the C windows temp.
    I have attached the filelist but it doesn't seem to contain much info. I still cannot delete the file (which is in the trash). Can that file still cause problems while in the trash? Mariah

    I thought the file was still in C:\windows\temp.
    When you say trash, you mean Recycle Bin... right?

    So are you saying you cannot empty anything from the Recycle Bin? Like if you create a test file and delete it, does it show in the Recycle Bin? Can you delete just it from the there?
     
  31. mariah

    mariah Private E-2

    When you had me run ExplorerXP I was able to delete the files but they stayed in the recycle bin and I cannot get rid of them.....when I try to empty the recycle bin I am told I do not have access to those files. I can delete all other files from the recycle bin, just not those. Those files are: ~aproposO, AutoupdateO, and the temp file. Mariah
     
  32. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Make sure your first empty all other files from your Recycle Bin.
    Now download the attached ZIP file and extract the getRECY.bat from it into your c:\ folder.
    The double click on the .bat file to run it. It will create a file named recycle-list.txt in the same folder ( that is C:\recycle-list.txt ). Upload that file back here as an attachment.

    After completing steps from my previous message. Please do not do the steps in this message until you do the other one. I want to see the output from that file I asked you to attach.

    Re-download and install ExplorerXP a new version (1.06) is out the fixes some bugs. Including a few I reported to them.

    We may be using this again to try something. In fact...let's just try it. Run the new version of ExplorerXP and navigate your way into C:\Recycler and try to locate the problems files. They are likely in a sub-folder with a very long name beginning like S-1-5-21-......

    When you find a file, click on it once to select it and then click the Edit menu and the select Delete Permanently

    Does that work!

    One more question. Should I now turn system restore back on?

    Mariah
     
  38. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    You're welcome!

    I would reboot! Run a full scan with Ad-Aware SE and your antivirus application. Fix anything found (hopefully nothing but cookies and MRUs) . And if clean, yes turn system restore back on.

    Make sure you work thru the steps in How to Protect yourself from malware! to help avoid future problems.
