I'm running an old computer with XP Service Pack 3. The Task Manager shows 51 processes, and one or another turns on every minute or so. Each shows 1-5% CPU Usage for a few seconds. This has become a nuisance, since I can hear the cooling fan turning on and off constantly. One of the programs is wmiprvse.exe; I've downloaded the Microsoft fix that is supposed to prevent this, but without effect. I also performed an Avast boot time scan, and Avast did not identify this program as suspicious. A search found 7 copies of this program (sometime as part of a Service Pack), but only one was the C:/WINDOWS/System32/wbem copy that is supposed to be the operative one. The Task Manage list also has 8 copies of a program named svchost.exe with several USER NAMES. Finally, I don't need this computer for the Internet. If this problem is related to checking for updates, please help me remove those processes. Thanks.
