High CPU utilization

[louis]

In my task manager Ive noticed that lsass.exe and
svchost.exe combined on SYSTEM user name are using my cpu
at 100 percent. How can I fix this?

Thanks for your time

I would suggest a virus scan with updated software.

I have same problem. When I kill svchost.exe the problem
stops - but so do some of the pc functions (e.g. audio).
On occasion, running spybot and or adaware will fix but
it occurs the names time I reboot. In that mode right
now and cannot get below 88% usage.
