svchost.exe normally causes no problems with my computer except during and after installing Windows updates. After installing Windows updates, it consumes around 50% CPU for a long time.

Located in System32, it's filesize is 27,648 bytes.
Looks pretty legit, but consumes a lot of memory. & zxin &
Its a windows process, its essential, dont delete it (if you delete it you wouldnt be able to read this anyway) &
Earlier message - I didn't mention that Norton help said it appeared to a program removed last year from my computer - which is when the Norton blocks started. It looks as though Windows7 wants to access its files to repair something but Norton blocks it.
Norton 360 InetSecurity blocks this file. When I shut down I get a message "Waiting for background programs to close" & Task Host etc etc. Takes a long time to close down. I get messages from Norton about "High Disc Usage" when I'm doing nothing much - pops up for a time and this message ceases. & nojo &
