According the the article above it is a virus!

"W32/Sonebot-B drops a copy of itself to the Windows System32 folder with the filename WMIPRVSE.EXE and sets the following registry entries to run the copy on system restart: "

Use antivirus with lastestupdate scan your computer now.

I check the page but it's not a virus
I have pc cillin with the latest update and i also did an online scan with mcafee but no virus found..
itss now running. the pc is very slow..
gpt 10 instances of it running now

wmiprvse.exe is not a virus, and it is not unusual to have more than one instance of this program running. This is a new file that was introduced in windows XP/2003. It is the Windows Management Instrumentation Provider Service and it is an essential Windows XP/2003 service which will start whenever software requirires its facilities.

There is almost never a problem with the file itself. Uusually there is a problem either with the WMI provider process or a hardware problem or incompatability that is causing the excess usage.

First see if windows update has any WMI related fixes. If there is no luck there you need to look at some of your hardware. Particularly any network card that may be installed. It may be that the drivers for you network card are bad or it could be a problem with the chipset itself. If it is a problem with the chipset, the only fix is to replace the network card. The way to tell if this is the problem, is to remove the hardware from your system and make sure that the driver is uninstalled in windows xp. If your problem does not return and you already tried updating the drivers, it's time to replace the network card.

Just a followup to clear up a previous statement. The network card does not have to be on the pc that is having the problem. Any bad network card on the network can cause this behavior.
