svchost.exe grabs CPU at 2 am every night?

    Sometimes when I'm up late working at my computer it suddenly becomes
    sluggish and almost unresponsive for several minutes. After several
    instances of this, I noticed that this tends to start at 2 am pretty much
    every time it happens. Task Manager shows one of the several svchost.exe
    processes using most of the CPU when this happens.

    Is this a Windows bug? Or just one of those annoying Windows annoyances?
    Is there anything I've installed that might be responsible? As far as I
    can tell, that svchost.exe (or one with the same size, anyway) is there
    all the time along with several others that have different sizes but the
    same name. Only occasionally does that one misbehave and start hogging
    the processor.

    P.S. Is there any jurisdiction where it would be legal to shoot the guy
    with the really irritating high, screechy voice that's in that *#&! Juicy
    Fruit ad that every TV station plays several times an hour, 24 hours a
    day, for the past several months? I know that wouldn't magically stop the
    pre-recorded ad from existing but it would be ever so cathartic and it
    might deter anyone from ever helping to record another similar ad ever
    again. :p

    Could be your anti-virus doing an update. Could be some utility
    software you configured to have it run a scheduled task, like a backup.
    Multiple services get rolled up into one instance of svchost.exe. See:

    http://support.microsoft.com/kb/314058
    http://www.howtogeek.com/howto/windows-vista/what-is-svchostexe-and-why-is-it-running/

    Use SysInternals' Process Explorer to dig into what services are rolled
    into one instance of svchost:

    http://technet.microsoft.com/en-us/sysinternals/bb896653

    You can right-click on a svchost.exe process (you probably have more
    than one), and look at its properties to see what services got rolled up
    into that svchost.exe instance. You can hover the mouse over a
    svchost.exe instance to see the list of embedded processes but it could
    be a long list. Some may have 1 or a few services rolled into them but
    some might have a couple dozen. When you right-click and look at the
    properties, look under the Services tab to see them.
