svhost.exe

[Mikey]

Hi,

I noticed that svhost.exe is spiking up the CPU
utilization to 100%, even rebooting does not correct this
problem.

Does anybody know the cause and if any way to fix this.

Thanks in advance for the help

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.

it may be normal to have several instantces of svchost
running but its not normal for them to use all of the cpu!
you most likely have spyware on your computer that is
connecting to the spy.
