What is this file? Is not a virus? What anti-virus software can kill?

Users questions: Recently found that the computer is very slow to open the process found at the bottom of a "SystemIdleProcess" the image, the user name is system, memory for up 8% 90, but it is not the end, who knows this is what ah? Is not a virus ah ? How do?
Experts answer:SystemIdleProcessSYSTEM not a virus! SystemIdleProcessSYSTEM not really a process that is out of the core virtual, multi-tasking operating systems have it! Progress in the absence of available Process, the system is running empty, and at that point SystemIdleProcessSYSTEM running! It is the cpu occupancy rate the greater the CPU resources available for distribution, said the more the smaller the number, said CPU resource constraints. Memory for 90 to 8 percent is normal Like, state your computer "load" very light, if only by a few too, then won `t really trouble.
