SVCHOST - loads of CPU at startup

Intermittantly, when I start XP, SVCHOST.exe seems to use
loads of CPU (90+%) and a large chunk of memory.
Everything has to wait until this is reduced before it
starts working.

Any ideas ?
 
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, as you report, 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.
