Windows Idle process

My PC is very slow I looked at my process and there is a "windows Idle process" which uses 87% of memory.
I have read some forum that my memory was free and on the other the opposite. If someone can tell me if I have to kill the process and if so how. Thank you

It is in fact normal, it is a process which indicates there are 87% free memory.

Hi,
I would like to share my thoughts with this discussion.I think Security task manager indicates all running Windows tasks including embedded hidden functions (e.g. keyboard , autostart entry). A unique security risk rating indicates the likelihood of the process being potential spyware, malware, keylogger.
