HI,
A program called svchost is causing my cpu usage to climb
to 100%. i am working on a pentium 3 500mhz cpu. I have
allupdates and service packs installed for xp and scanned
for viruses many times. Can you help me to solve this
problem?

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.

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.
