    Hi all

    Glad I found this forum. Hoping one of you uber smart people can help me figure out wtf is going on in my computer. Long story short: I have a Seagate external drive hooked up. I back all my data up to it. The other day I accessed it and to my shock ALL FILES were gone. Poof. We're talking thousands of files. Weird though, the folder structure/tree was still completely in tact!! Every folder is there, it's just the files that are gone. I used Recuva This and got about 60% of it back. The other 40% is gone forever I guess. Very sad as there were about 500 family images that we lost.

    Anyway, I add more files to this drive about three days ago to test. Sure enough they TOO are gone now but their folders are still there! Ugh! Important to note these files are NOT going to the recycle bin for some reason. They are just being zapped from the drive somehow.

    SOMETHING/SOMEONE is making my files disappear. This drive is NOT being shared on the network. I ran scan disk and no errors were found. Here is my HT log:

    Logfile of Trend Micro HijackThis v2.0.3 (BETA)

    Welcome to Major Geeks!

    Please read ALL of this message including the notes before doing anything.

    Pleases follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and attach the requested logs when you finish these instructions.

    • **** If something does not run, write down the info to explain to us later but keep on going. ****
    • Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.


    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    Helpful Notes:


    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:

    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
    3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this aother user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:

    Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.

    SOLVED: Was a virus named Nod43 and Nod143.exe. First I had Hijackthis kill it, then I removed all instances of it from my registry. My internet connection is 40% faster now and my files are no longer disappearing. Now I'm going to change all my credit card numbers because there's no telling what this nasty virus was doing.

    I should add: AVG and Avast did NOT catch this virus

    I hope you are not currently keeping both AV programs on your system. I can only suggest that you go ahead and finish the instructions so we can check that all traces are gone. Otherwise:

    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 real-time protection. They are useful as backup scanners.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 /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    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. 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.
    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 ato create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:

    Ok, I thought I would follow up for posterity. I found out what the problem was. USB port overload. I was running too many devices through a USB hub. That's what caused the files to disappear. Problem is, they weren't gone when I thought they were. If would have just rebooted they would have returned. But no, I panic'd when I couldn't get answers and mined the disk with recovery software, grabbed what I could get, then -- at th behest of Seagate support -- reformatted my drive. Oops. Data gone forever. Really sad. Had just never heard of USB hub overload and didn't ever think that could be a possibility. Lesson learned. Hope this saves someone some headaches some day.
