Excessive use of cpu by svchost.exe

[GianCarlo]

hi,

I have a question might be wrong what I am asking but i have seen this with my system.
Excessive use of cpu by svchost.exe
My svchost.exe has been using maximum CPU usage. I don't understand why is this happening?
What should I do in this case?


Thanks in advance.

When you run Windows Update to scan for updates that use Windows Installer, including Office updates, you may experience a memory leak, or you may receive an error message for the Svchost process

The problem that the "Symptoms" section describes was corrected in Windows Update Agent 3.0 and in update 927891. These updates were distributed through Microsoft Update in June and July, 2007. If you are still experiencing a problem that resembles the one that this article describes, it may be a different problem.

These problems may occur when you try to scan for Microsoft Office updates. You may also experience these problems when you use any one of the following update mechanisms:

* The Microsoft Update Web site.
* Automatic Updates through the Internet or through Windows Server Update Services (WSUS).
* Microsoft Systems Management Server Inventory Tool for Microsoft Updates (SMS ITMU).
* Microsoft Baseline Security Analyzer (MBSA).
* Any application that performs update scans by using the offline scan CAB file (Wsusscan.cab) that uses the Windows Update Agent (WUA).

I don't agree that this only causes due to Microsoft updates.
You must also consider that this problem might cause due to a Virus or Trojan.

Again you need to monitor the processes in Task manager - processes.
Find processes from all users & find offending SVCHOST.exe

You need to go through these documents for further understandings:
