Hello

My machine is responding really slow now.After I run Process viewer
program,here is what I find

Process:Idle Pid : 0x0 Cpu :76% Desciption:system idle
Priority:0 Thread :0
Properties : no path , no command line , no current directory
             no parent ,no version

Did my machine get infected with a malicious code,How come a process
running idle can take up to 76% of Cpu ?

Thank you again!

Baba
