Greetings --

    It's perfectly normal to have several instances of Svchost.exe
running simultaneously.

    However, if Svchost.exe is using a large portion of your CPU
cycles, it has most likely been "hijacked" by a worm or Trojan. Have
you tried using a decent antivirus application with the most
currently-available virus definition files? A strong candidate would
be W32.Welchia.Worm.

W32.Welchia.Worm a.k.a. W32/Nachi.Worm

  Because many of the newer viruses and worms can disable antivirus
applications whose definitions weren't up-to-date, try using one or
more of the free on-line scanners to double-check your system.
