svhost

I am connecting to the internet, after made a connection the svhost service uses the cpu 100%, and the pc is not responding also dead slow, how can i over come that, any security patches are available for that.... -Thambidurai

Whenever i logged on to the windows 2000 srv, i saw the HDD accessed by some processes more than 1 min, the LED is blinking, i watch the cpu usage inthe task manager the 2 svhost and winlogon processes uses utilizes the more cpu time, is anything wrong with this???? - Thambidurai
