    I've been having a major problem over the past few days with a virus called svchosts.exe. It appears to be some kind of virus or trojan horse that runs at startup through the Personalized Settings. I'm not sure what exactly its doing, since my computer has not shown a lot of ill effects, but I have noticed some slowdown and occasional shutdowns which could be to do with this.

    The file is supposedly located at this location-

    C:/WINDOWS/WINBOOTERR/SVCHOSTS.EXE

    I've looked for this directory and it isn't there, even when showing hidden files and folders.

    I have tried everything to remove this virus. I did a virus scan with AVG, it detected the virus and moved it to the Virus Vault, but its still running at startup. I tried using Spybot Search and Destroy which also picked it up, I removed it, but its still running. I also tried removing all instances of the file from the registry with regedit, but it is still there.

    Can anyone give me any advice to try and get rid of this very persistent virus, before it does any serious damage. If it's any help I'm on Windows XP Service Pack 3.

    Here is my HijackThis log-

    Bump. I also wanted to mention that I've tried removing this virus with Windows Security Essentials as well, but despite removing the virus it came back at startup again.

    Hello there :cool: Welcome to the TSG Forums.
    My name is NeonFx. I'll be glad to help you with your computer problems. Logs can take some time to research, so please be patient with me.


    Please note the following:
    • The fixes are specific to your problem and should only be used on this machine.
    • Please continue to review my answers until I tell you your machine appears to be clean. Absence of symptoms does not necessarily mean that the system is completely clean.
    • It's often worth reading through these instructions and printing them for ease of reference. I may ask you to boot into Safe Mode where you will be unable to follow my instructions online.
    • If you don't know or understand something, please don't hesitate to say or ask!! It's better to be sure and safe than sorry.
    • Please reply to this thread. Do not start a new topic.



    Step 1

    Download OTS to your Desktop

    • Close ALL OTHER PROGRAMS.
    • Double-click on OTS.exe to start the program.
    • Check the box that says Scan All Users
    • Under Basic Scans please change the radio button under Registry from Safe List to All.
    • Under Additional Scans check the following:
      • Reg - Desktop Components
      • Reg - Disabled MS Config Items
      • Reg - NetSvcs
      • Reg - Shell Spawning
      • Reg - Uninstall List
      • File - Lop Check
      • File - Purity Scan
      • Evnt - EvtViewer (last 10)
    • Please paste the contents of the following codebox into the Custom Scans box at the bottom
    Code:
    %SYSTEMDRIVE%\*.exe
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll
    iaStor.sys
    nvstor.sys
    atapi.sys
    IdeChnDr.sys
    viasraid.sys
    AGP440.sys
    vaxscsi.sys
    nvatabus.sys
    viamraid.sys
    nvata.sys
    nvgts.sys
    iastorv.sys
    ViPrt.sys
    eNetHook.dll
    ahcix86.sys
    KR10N.sys
    nvstor32.sys
    ahcix86s.sys
    nvrd32.sys
    symmpi.sys
    adp3132.sys
    mv61xx.sys
    /md5stop
    %systemroot%\*. /mp /s
    CREATERESTOREPOINT
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\System32\config\*.sav
    • Now click the Run Scan button on the toolbar.
    • Let it run unhindered until it finishes.
    • When the scan is complete Notepad will open with the report file loaded in it.
    • Click the Format menu and make sure that Wordwrap is not checked. If it is then click on it to uncheck it.
    Please attach the log in your next post. To do so click on the blue "Reply" button or "Go Advanced" and click on the "Manage Attachments" button

    Step 2

    [​IMG] GMER Rootkit Scanner
    Please download GMER from one of the following locations and save it to your desktop:
    • Main Mirror
      This version will download a randomly named file (Recommended)
    • Zipped Mirror
      This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
    • Disconnect from the Internet and close all running programs. Make sure you disable your security programs as well, as they may interfere with the program.
    • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
    • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

      [​IMG]
    • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
    • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
    • Now click the Scan button. If you see a rootkit warning window, click OK.
    • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
    • Click the Copy button and paste the results into your next reply.
    • Exit GMER and re-enable your security programs when done.


    If you have trouble running GMER, please try running it in Safe Mode. To get to Safe Mode you'll need to repeatedly tap the F8 key on your keyboard as you turn your computer on until a black and white menu appears with the option.

    If you continue to have trouble with it, try running it without the "Files" scan checked.



    Again, if the results are really long, please attach them using the instructions I gave you at the end of step 1. This is to avoid having to scroll down the page too much make the space cleaner.
