I think I have the same problem (see my message Windows
Low on Memory - but it isnt). Task Manager shows
svchost.exe using a lot of memory ( and three copies of
it running). Norton doesn't indicate this is a virus
though.
svchost is merely the program used to load a whole slew of services,
each instance running several, and one has to find out which is the one
causing the heavy load. It is not much help to look for which ones are
running, as there is nothing to show the cpu or memory use for
individual services. THere may be 4 or 5 instances of svchost running,
and a total memory use of 30 or 40 MB is normal enough
What you can do is go to Control Panel - Admin tools - Services, look
down for possible candidate that are 'Started' and try (in the left
panel) a Stop to see the effect. If either the CPU usage continues or
something stops working, put that service back. When you have found a
likely cause, double click, set Startup type to Manual for the moment.
If such a service then does start on a later occasion, it is because
something is needing it.
You can probably do without the following unless you are on a network:
'Background Intelligent Transfer' and 'Routing and Remote Access' are
two that seem to have been implicated in heavy CPU use in the past
Alerter
Background Intelligent Transfer
Indexing Service (unless you want all Office documents indexed for
faster searches on basis of contents)
Messenger (this is *not* the Instant Messaging program)
Performance Logs
QoS RSVP
Routing and Remote Access
and unless you go through a router that supports Net address translation
(NAT) the pair
SSDP Discovery
Universal Plug and play
Anything else that could usefully be set as Manual probably is already
anyway
