System shut down

[Tony]

Help,
Every now and then I get a pop up stating my computer is
shutting down with a reason of something to do with
CVSHOST & system32 (think its right forgot to write it
down!!)it has a coundown and automatically shuts down and
restarts the computer. Only happens when I am online.
