worm-koobface alerts

    Hi there,

    Having a problem with my registered SpySweeper W/Antivirus giving file alerts for worm-koobface whenever I finish a web session and run CCleaner. This does not happen every time, but it happens often. The file it quaranines is always in C:\Documents and Settings\Administrator\Local Settings\Application Data\Mozilla\Firefox\Profiles\wgo54x7s.default\cache.

    I do not social network at all, don't have a facebook account, and am careful about clicking on any suspicious links. I am also the only user on this computer.

    This never shows up in a scan, only when CCleaner is run. (set at 7 passes) I have run several online scans with OneCare, Housecall, and Eset, and nothing shows up. I have also used RootkitRevealer, Gmer, RootRepeal, and Sophos Anti rootkit, and nothing out of the ordinary shows up.

    I recently renewed my SS subscription, and just in case, I uninstalled it and redownloaded it again from Webroot's site. I'm wondering if this is just a false positive or if I truly do have a problem..

    Just for good measure I have followed the READ & RUN instructions and the logs are attached, except SAS found nothing, therefore no log was generated. In the whole process nothing was unusual except a file deleted by Combofix, comctl.oca. Is this file a problem?

    I hope that's enough information, and thanks in advance.

    1. Before we continue I would like for you to ensure that MGTools.exe is indeed directly on your C Drive and not in any other location, such as the desktop where you have it.

    2. I would like for you to use MSConfig to put this machine back into normal start up mode. Only then continue with the below.

    The log is retrievable from this location and I would like for you to attach it anyway regardless of whether it found anything ot not.

    3. Do you have any idea what all the below are? I only pasted a few lines in, there are many of them:

    4. Please go to Add/Remove programs and uninstall the following software:

    • Spin Palace Casino
    • Club World Casinos

    5. 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::
    
    File::
    C:\WINDOWS\system32\QKYAVNU
    c:\windows\winstart.bat
    
    DirLook::
    C:\MGS
    
    • 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.

    6. 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 and also attach the log from Combofix. and SAS.

    7.Let us know of any problems you may have encountered with the above instructions and also let me know how things are running now!

    8. Let me know if the threat is still being detected by SS.

    Hi,

    MGT has been moved to C:, sorry about that.
    MSConfig set to normal, didn't realize that installing recovery console changed it.

    MGS is Microgaming, a Casino I play at, never had a problem with it, but uninstalled it anyway via CP, although it leaves behind a lot of stuff that has to be done manually, which I didn't do, sorry. I have not been there since this started, so doubtful it is the cause.

    Clubworld is also safe, but uninstalled per your request anyway.

    QKYAVNU I believe is part of my Power shot Camera software, but ran the CF script as requested.

    Ran the MGtools\GetLogs.bat file.

    All requested logs attached.

    Thanks

    Forgot to add, I did get one error with CF for Process.dll not found, as I don't have framework installed.

    Thanks

    1. Reinstall your casino software then if you wish. WebOfTrust gave a bad report about it and I didn't know if it was the cause of your problems but I think as you say it's okay.

    Not sure about that so let's restore the file and then I can take a look at it.

    2. 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::
    
    DeQuarantine::
    C:\Qoobox\Quarantine\C\WINDOWS\system32\QKYAVNU.vir
    QUIT::
    
    • 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.

    The DeQuarantine.txt will be in on the C: Drive. Please attach it.

    3. Could you please get this: QKYAVNU into a zipped file and attach it for me in your next post? To do this, see the below:

    Please go to start > Run and paste in the following:

    log retrievable @ C:\collect.zip. Please also attach this.

    4. 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 and also attach the other logs I requested.

    5. Is spysweeper still detecting the problem?

    The collect.zip file is too big to upload, other logs attached.

    Well, all I can say is let's give it some time and see if Spysweeper still locates the threat. Then we can deal with it accordingly. Let me know.

    Just to be on the safe side, I deleted QKYAVNU, if it is a required file I can always re-install the camera suite. Viewing it in notepad had several references to camera related software, but one never knows.

    I ran CCleaner after deleting it, and got the alert again for a file in Mozilla cache, strange, as this is the only site visited since the last scans. :confused

    If the logs were clean, I hope this is just a false positive, and as stated in the OP, I just renewed my SS subscription and updated to the newest version.

    I might try opening a ticket with webroot and see what they have to say.

    Then it sounds legit, only my reseach on the file turned up nothing, hence my desire to kill it.

    Yes you could do this and in the meantime I will have a whisper in Chaslang's ear and see what he can tell us. :)

    Understandable, a google search of the file name yielded nothing, and I'm always suspicious of files with random letters in the name also.

    I did submit a ticket with webroot, will see what they say.
    I appreciate the help thus far, I hope he can shed some light on this.

    Hmmm.....

    Interesting development, as I was reading through some of the posts here (it's always good to learn), I got an alert from SS file shield in the middle of browsing. Same thing, worm-koobface, quarantined from Firefox cache.

    I tried a little experiment after that, browsed a few pages here and elsewhere then closed Firefox. Went to the cache file and performed a security sweep on it, and it came up clean. Then I ran CCleaner and got an alert, the quarantined file was from the Firefox cache. :confused

    Try this:

    Now let's flush the Java Cache

    • Click Start > Settings > Control Panel
    • Double click the Java icon (be patient, it may take a while to open)
    • Now click the General tab and under the Temporary Internet File area
    • Click the Settings button and then click the Delete Files... button.
    • In the next popup click OK.
    If you have multiple Java plugin icons in Control Panel follow the above to clear all their caches.


    Now let's flush the FireFox Cache
    To flush your FireFox Cache:

    • click Tools
    • select Options
    • select Privacy
    • in the section labeled Private Data click Clear Now

    Now let's flush the Internet Explorer Cache
    To flush your Internet Explorer Cache:

    • click Tools
    • Internet Options
    • Now on the General tab and click Delete Files and select Delete all Offline content too
    • Click OK.
    • When it finishes Click OK.

    How are things now?

    Cleared Java cache (it was empty)
    The button you described in Firefox does not exist, but I did clear the history and cookies.
    Cleared IE cache (it was empty)

    Interesting, I have seen the private data button there before, but it seems to be missing. There is a clear offline files button under advanced/network, and nothing listed in the exceptions file. I'm running Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6.

    I did update Firefox not long ago, I wonder if I got a corrupted version, however I did uninstall CCleaner and Firefox and re-installed them two days ago with no change. I run CCleaner on a regular basis, and it clears all the cache automatically, Firefox, IE, and Java are all selected, in fact that is when this file alert pops up, when it deletes the Firefox cache.

    Just a thought, I have CCleaner set to NSA (7 passes), perhaps this is being detected by SS as a behavioral issue, but doesn't explain the alert while browsing here the other day. Perhaps a query to Firefox and Piriform might be in order as well, and with your permission I will link this thread so I don't have to go over all this again.

    I got a response from Webroot, they wanted me to do scans with SS, run bootlog, GMER, and WrLog and send them logs, which I did. Pretty much the same as your R&RMF. Still waiting for the reply.

    Thanks for the help so far.

    Haven't had time to run eset yet, it takes hours on my machine. :zzz

    I did get a reply from Webroot that finally addresses my question to them.

    He then went on to explain how to update the program. I have it set to auto updates and get new definitions every day, so I doubt updating will help but I did run the updates anyways.

    Will run Eset later today and post results. As referenced in OP, the last Eset scan was clean.

    Thanks

    Well, good to know, but I'll still hold off from giving you final steps for a little while. Let me know over the next day or so about how it's going. Thanks, Kes :)

    Hi Kes,

    Don't really need the final steps, already cleaned things up thanks.

    I did manage to capture one of the files that SS was triggering on, if scanned with SS there is no threat found, delete no problem either, but when I ran CCleaner to empty the trash it triggered the alert.

    Kinda confirms my suspicion that the problem lies with SS?

    Attached the file in case you're interested, and will update when finished with Webroot.

    Thanks for all the help. :)

    You're welcome. Here are the final steps anyway.

    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 used Pocket Killbox during your cleanup, do the below
      • Run Pocket Killbox and select File, Cleanup, Delete All Backups
    3. 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.
    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 6 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:

    Surf safely! And yes, so let me know what the upshot of the webroot reply was.

    Here is Webroots final reply:
    And a reply from the CCleaner forum:

    I tried to report this to Webroot using the supplied link in their reply, but only Piriform can report it and get Webroot to investigate. . There is a reply in the CCleaner forum from another user with the same problem:
    Sorry for the long post, but I want to get the information out there for the other users with this problem.

    Dangerous, thankyou very much for the information. I was not seeing malware in your logs and I knew your system was clean. Thanks for info you provided, I am sure it will be beneficial to others in the future! :)
