The system is always 100% cpu usage. I found there is some virus (or) spy is running, because the sent packet is more than receiv packet, I cleared with Xsoft Spyware, the system becomes normal but still the cpu usage shows 100% some spy is running in startup. I could not find virus or spy anyware. what is the soln?

Cpu at 100% could be spyware. Press Ctrl + Alt & Delete, if your cpu usage is 25 to 35 thats ok, any more than 45 and spyware could be on your pc. Download Spybot S&D and Adaware and you've got the basics covered. I've also noticed that Norton Int Security 2006 can do that also. Stay away from unknown spyware programs that are not well known, 90% of them are of little or no use. If your unsure if it's worth buying/trying just ask, were here to help. If your computer says, "Printer out of Paper," this problem cannot be resolved by continuously clicking the "OK" button.

*Correction, I meant to say if your processes in the lower left hand corner is 25 to 35 thats ok. If your computer says, "Printer out of Paper," this problem cannot be resolved by continuously clicking the "OK" button.

If you are saying the % in the main window is high, that is OK, it is talking about what is available to you in Idle mode. http://www.answers.com/topic/system-idle-process

If Windows Task Manager shows System Idle Process at 100%, it can also indicate program conflicts, corrupted system or program files, and bad or corrupted drivers. It doesn't necessarily mean you have malware, a virus, worm or Trojan. You could see if you have installed anything recently and try uninstalling to determine if that is the problem. Also, try individually stopping any applications that run to see which, if any, may be causing the problem. Be very careful stopping processes, though, as this may just lead to more problems. bugs
