Problems with svchost.exe

By maria_83

  1. Dear friends,

    Again I have a problem with my PC. When I start it, nothing works. I noticed from the Windows task Manager that the file svchost.exe is taking 100% of the usage. Now when I end the process everything's fine, but my sound files don't work, so I cannot listen to my mp3 or I see the videos without sound. If I post any of my logs they will be after I terminated the process, since otherwise I won't be able to do anything. Can you help me?
    Thank you very much!

    P.S.

    My AVG didn't find anything. I don't have Windows Service Pack 2 installed.
    Best regards

    Your system is infected with malware and you`re running an outdated version of Hijackthis. You also need to rename HJT as per the instructions.

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.

    Go and read the Viruses/Spyware/Malware, preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT, AVG Antispyware and Combofix logs as attachments into this thread, only after doing the above.

    Also, let me know the results of the AVG Antirootkit scan.

    Regards Howard :)

    Hello Howard,

    I did everything that you said, but unfortunately, nothing has changed. I'm posting my new logs.

    Your HJT log is clean.

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.

    If you have any further virus/spyware problems, please post in this thread.

    Regards Howard :)

    Thank you, but unfortunately, nothing has changed. When I turn on my computer the svchost.exe blocks the system. When I terminate it, my sound files won't work. Maybe I should reinstall Windows?

    Hi,

    What do you mean exactly by svchost.exe blocks the system? If you find it hogging up most of the resources, please try the following.

    Turn off your automatic updates.

    Try installing this updater.

    next, reinstall KB927891 here

    Then try turning updates back on again.

    I hope this helps solve your problem.


    Regards,
    Your friendly Momok =)

    Hi,

    Glad to be of help.

    This is with regards to your previous infection.
    Often times, an infection can occur again not due to the incompetence of programs, but because of user habits.
    May I recommend you to read this article.

    This can help to prevent future infections.

    Should you have any further problems, please post in this thread.


    Regards,
    Your friendly Momok =)
