w3wp.exe recently started taking up excesive CPU
Recently on my PC I have noticed that the process w3wp.exe is started and taking up an excessive amount of CPU (50- 90%). Looking into this it is a NETWORK SERVICE for IIS Worker process. Where I used to use the PC for web development I currently do not and cannot see why or what started this process.
I do ha a cloud back up drive attached to the PC, but this is being run on a separate service (WDBACKUPENGINE.EXE).
If I have a look at the resource monitor I can find the PID, but if I look at services under task manager I cannot see a related service with that PID.
I am a bit concerned that this may be a virus taking control of my IIS, but no scan shows any viruses.
So what starts w3wp.exe and how can I prevent it from starting automatically?

Allows me to keep IIS installed for future use
- detailed analysis of HTTP logs
- (possible) code review of pages ID'ed as long running processes (asp, aspx, php, etc.)
- process dump of AppPool(s) process(es) that is consuming CPU
- monitoring of connections to the server running IIS
- process/resource monitoring of server running iis
Just an FYI.
