    I have been trying to figure this out for 4 days now, I am usally pretty good at getting malware crap off computers but this one has me stumped. I am running windows 7 professional 64bit and cannot execute any .exe files, no virus scans, etc... only exe's that will run are 64bit programs, from what I can tell, I can run IE 64bit and photoshop 64bit but cant run firefox or any of my scanning programs. I've tried a few rescue cd's from different AV softwares to no prevail. I also have tried renaming exe's to .com .svr with no avail either. I can watch the task manager when I start a program, it will popup in the task manager then it will disappear about 3-4 seconds later. I have no idea what to do. Any ideas?

    PS:
    Also in safemode nothing will execute except same stuff that executes in normal mode.

    PSS:
    Also, it has thrown a few BSOD at me, but totally random.. it will also just randomly restart. I cant even find what the name of this thing is..

    Welcome to Major Geeks!

    Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
    There are 4 different versions. If one of them won't run then download and try to run the other one.

    Vista and Win7 users need to right click and choose Run as Administrator

    You only need to get one of them to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.
    1. Rkill.exe
    2. Rkill.com
    3. Rkill.scr
    4. Rkill.pif
    Once you've gotten one of them to run then try to immediately run the following.


    Download and save the below to your PC (save it anywhere you can find it. The Desktop is fine). Then double click on it to run it.

    AVPFind.bat

    It should take a couple minutes to run. You will see a black command prompt window while it is running and it should close when it is finished. Once it finishes, attach the c:\avplog.txt file that is will hopefully create as long as the malware does not block the batch file from running. (See: HOW TO: Attach Items To Your Post )


    Now download and Run exeHelper
    • Please download exeHelper to your desktop.
    • Double-click on exeHelper.com to run the fix.
    • A black window should pop up, press any key to close once the fix is completed.
    • A log file named log.txt will be created in the directory where you ran exeHelper.com
    • Attach the log.txt file to your next message.
    Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).


    Also please try running the below online scan:

    http://www.superantispyware.com/onlinescan.html

    Reboot immediately after scanning if it finds and removes anything. Let me know if anything was found. See if you can save a log with it.


    Then try running these instructions: Using MGtools


    Attach the below logs when finished with all of the above:
    • C:\avplog.txt - from AVPfind
    • a log from online SAS scan if you could make one
    • log.txt - from exeHelper
    • C:\MGlogs.zip - from MGtools
    The C:\ assumes that drive C is you Windows boot drive. If you boot from another drive, then use the correct drive letter above.

    Heres the avp log, I ran the exehelper but it didnt create a log nor did I see any text in the command prompt.. tried to run it again and it just poped up and disappeared immediatly. Also couldnt use the scanner nor mgtools, nothing happened with either of them...

    Try booting your PC into safe boot mode. Then do the below.


    Run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:
    • C:\MGlogs.zip

    It would not run, even in safe mode. Nothing pops up, just acts like nothing happens.

    Did you shutdown UAC and is it still shutdown?

    What happens if you do the below?



    Please click Start, All Program, Accessories and you will see ( among other things ) a Command Prompt entry.
    • Right click the Command Prompt entry and select Run As Administrator.
      • It is critical that you run it this way.
    • If you do this properly, a command prompt window will open with a title of Administrator Command Prompt.
    • Enter the below commands at the command prompt each followed by the enter key. The bold black are commands. The purple/brown is merely informational.
    cd \MGtools <-- this changes to the MGtools folder and the prompt should change to C:\MGtools>
    GRK64 <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.
    SN64 <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.

    Now I am getting a bsod saying IRQL_LESS_OR_NOT_EQUAL_TO or something of that sort when I log into safe mode.

    Sounds more like you have problems with your Windows installation that needs to be repaired. This may not be an issue for the Malware Forum to work on. What exactly happened when you tried to use one of the special boot CDs?

    Do you have your Win 7 boot DVD?

    Im pretty sure its malware/virus. I am not exactly sure what happened, as my sister seems to just get on my computer as she wishes. When I ran AVG rescue cd it found a few objects, but it didnt remove them. I manually removed them later after it was done. The other one I ran, bit defender, never found my harddrive, which was because I was running them off a usb flash drive Im pretty sure, but never could get it to find my partions. As far as my boot disk, I have the Win 7 disk somewhere around here, I've spent all day looking for it, otherwise I would have already reformatted.

    If your PC was properly password protected and if she does not have her own login, then she could not do this. Was your PC password protected?

    Exactly what we removed. This could be potentially be the cause of problems.

    If you cannot run anything, then we cannot do anything. This would likely lead to suggestions of trying to do a System Restore and if that does not work a repair. And if that does not work, a reinstall.

    Yes it was, she said she was under guest account, but sometimes I forget to logoff my name.

    It was a folder in the c drive named Downloader.

    I understand that. I have already attempted a SR, twice actually, and after the second time all my restore points disappeared. I also had a complete image backup of my hd saved on a separate partion and somehow it isnt there anymore either.

    Guest account is disabled by default on newer versions of Windows and if it exists and is not disabled, it should be disabled. It is a security risk.

    Security risk and if you have problems with people using your PC and you don't want them to then have it revert to the welcome screen and be password protected after some number of minutes of inactivity.


    That is all it said? No file names were listed? And was this folder right in the root folder of drive C or was it under Windows or somewhere else? May not matter too much now since we may not be able to do anything about it.

    Then it still sounds like more than just malware. This is not typical of any infections we have seen. How are you checking to see if the partition is there if your PC is not running properly?


    If you can boot up in normal mode and execute basic commands, what happens if you try what I suggested in message # 7 in normal boot mode?
