svchost.exe (netsvcs) high memory utilization


A user is complaining about his computer slowing down at least twice a day for up to twenty minutes each time

During these occurrences the memory used by a particular svchost.exe climbs to 1GB
Please see the attached images to view the services concerned, and memory status during slowdown

I have checked his Windows 7 computer Lenovo Thinkcenter M90 ( i3 CPU 530 2.93GHz) and all seems clean and up to date - I updated the motherboard's firmware

I ran Malwarebytes and all is clean

I'm not sure if I should be worried by the presence of 81 hardware faults ?

I have checked the events log and detected nothing out of the ordinary or cause for alarm

The diagnostics-performance log however has numerous warnings and a few critical errors:
100, 101, 200,201, 500, 501

Any ideas ?

If you are sure the computer is clean, look in the Anti Virus software. It may be doing scans during the day and that can slow the computer down when the scan is running.

Look to see if Indexing is running as well.

Clean up temporary files (Disk Cleanup in Admin Tools), run Disk Defrag (also in Disk Tools) and scan once more (in Safe Mode) for viruses and malware.

You may want to run Process Monitor on the machine.  WHen you do so, you'll be able to see everything running under that instance of svchost.  Just get the PID from task manager and look for it in ProcMon

svchost.exe is usually not the problem of high CPU usage by itself.  It is only opened by the other processes it is "hosting".
