    svhost.exe*32 High CPU Usage?


    Ok so for the last couple of days my pc has been constantly running at 83% cpu usage on idle, as i type this it sits at 83% and my pc is no pig its 6core, 8gb 1600mhz ram, ssd, gt680 so im used to cpu usage being 0-1% while idle or net surfing.

    I havent noticed anything in particular to cause the problem it just started happening, have read up on the net but not been able to identify what cause this.

    I tried to run resource monitor and i know its svhost.dll thats using it but it wont tell me what service under svhost that is causing the high usage.

    I will attach screens so you guys understand what i mean.


    I should also mention it happens nearly all the time but after a restart it will sit at 0% until i do something and if i run minecraft after about 1 minute it will jump to 100% until i quit then drops to 83 it happens everytime 100% of the time, but what i dont understand is i have been running minecraft for months so i dont think its tied to that.

    Anyway here are the screens.

    Hello VivaLaMikey,

    After looking at your screenshots and realizing that you have a 64 bit version of Windows installed, a thought occured to me.

    That CPU consuming svchost.exe*32 process does not belong on your system!

    On a 64 bit Windows system, all legitimate svchost.exe processes do not have the *32 suffix attached to them as they are native 64 bit processes used by Windows that act as containers for groups of services that run on your Windows 7 system.

    I see that you are using AVG as your antivirus.

    Remove AVG completely from your system by using this removal tool:-


    (If you're using AVG 2011)
    http://download.avg.com/filedir/util..._2011_1322.exe (32 bit)
    http://download.avg.com/filedir/util..._2011_1322.exe (64 bit)


    (If you're using AVG 2012)
    http://download.avg.com/filedir/util..._2012_1796.exe (32 bit)
    http://download.avg.com/filedir/util..._2012_1796.exe (64 bit)


    Then download and install MSE and MBAM from the following links and perform a complete scan of your computer with each application, one at a time.


    Download Microsoft Security Essentials (MSE) from here:
    Microsoft Security Essentials - Free Antivirus for Windows


    Download the updates for MSE from here:
    Install the latest Microsoft Security Essentials definition updates - Get the latest definitions - Microsoft Malware Protection Center


    Download malwarebytes from here:
    Download Malwarebytes Anti-Malware 1.61 - FileHippo.com


    And the malwarebytes updates from here:
    http://data.mbamupdates.com/tools/mbam-rules.exe


    Hope that helps!

    So looks like i fixed it, shortly after posting i decided to do a scan with AVG it quickly told me that services.exe in my system32 folder was a trojan, so i deleted it (knowing full well it would kill my system).

    Sure enough BSOD on startup so i inserted system repair disk did the repair, rebooted and it all seems fine.

    Will still monitor over next couple of days as some forums i read say that its fine for a week or two then issues re-arise.

    Have attached a screen of a much more healthy looking Task Manager minus svhost*32 (you were right :P)
