An SVChost process on my Windows XP SP3 started running between 15% to 35% active while the PC was not in use. When I stop Secunia, the utilization drops to nil. This level of activity kept my disk defragmenter - Diskeeper - from running. It also was a drag when the PC was otherwise active.

I have two other PCs running Secunia PSI with no problem. Any thoughts on what could be going on on my PC. The SVChost process is the one that runs the "netsvc" tasks.

I ran Nortin Internet Security 2012 and MalwareBytes Pro full system scans in Safe Mode. There were no findings.

I don't remember for XP but on later systems the netsvcs group includes WIndows Update which would be started by PSI during a scan. I wouldn't expect it to be running all the time.

If you want to dig a bit further, you can use Process Explorer to find which service is using the CPU.

You can also use the "tasklist /svc" command. There are 30 services running under the SVChost task that gets over stimulated. I can't tell which service or services is/are active.

I do know that the symptom showed up on or after Jan 5,2012. I didn't install any programs around that time.

I'm not running any exotic programs. Secunia CSI has always worked just fine - until now.

Are you using CSI or PSI?

You can find which service is using CPU with Process Explorer.
Click on the File menu and click 'Show Details for all Processes'. Then double click the svchost.exe which shows the high CPU usage.
Open the 'Threads' tab to get a breakdown of the activity in the process.

We must be using different versions of Process Explorer. I don't see the option that you described under FILE.

What I have done is to download and re-install Secunia CSI. The problem appears to be resolved.

It's probably because you have XP and are already running as an Administrator. You should still be able to look at what's happening inside a svchost by double clicking it.

Anyway, it looks like you're back to normal now.
