Svchost.exe using 99% CPU, help!

I've cleaned the pc from viruses, etc. and all seems good except it's still slow. A quick look at task manager tells me the SVCHOST.EXE process is using 99% of the CPU. Is there anything I can do to investigate why? Thanks very much!!!

  6. um ive disable all non essential services in services.msc but the remaining 4 svhost i cant disable without screwing the com-puter up as there essential.

    I read in a networking security book that workstsation should b disabled cos it can be comprimised. I give up
