Greetings --

There is no legitimate file/process called "svchots.exe." Are you
sure you spelt it correctly? There is supposed to be multiple
instances of "svchost.exe" running.

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.

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.
