100 % CPU Usage on internet connectivety

[rajiv juneja]

Hi,
I use a wireless landphone connection to connect to internet.

My problem is that most of the times(approx 60-70% times) I connect to
internet my CPU Usage goes upto 100% due to which my internet connection
speed and other processing gets affected considerably. Sometimes this
problem occurs a few minutes after connectivety and sometimes even later.

On checking it thru task manager I see that a process called svchost is
consuming about 90-95% of the CPU Usage.

This problem persists even after i go offline and even if i logoff and logon
again. Only when i restart the computer the CPU Usage gets back to normal.

I have a feeling that my anti virus has to do something with this but am not
sure. By the way I am using symantec anti virus corporate edition 8.

Please advice.

I also tried some troubleshhoting myself and found that svchost is actually
an exe file located in %windir%/system32 directory and that some services
like 'RPC', 'networkconnections' and 'Removable Storage' use this file as
there 'path to executable' (which i found after opening properties dlg box
of
respective services in services tool of computer management).

And coinidentally during my internet connectivety RPC service stops quite
frequently which I have to start manually. But the CPU Usage does not lessen
even after restarting this service.

But apart from this I am still not able to make out what exactly is going
on.

And yes I forgot to mention that during internet connectivety I come accross
a lot of virus (almost always w32.spybot.worm) in my TFTP files as notified
by symantec antivirus notification messages, which are quarantined by
symantec and later
deleted by me.

It is NOT due to your "internet connection SPEED"
but due to some (likely buggy or poorly written)
application or service that is likely trying to take
advantage of that connection.

For the OS itself (Win2000) you should generally
have all of the Service packs and most all hotfixes
installed.

On checking it thru task manager I see that a process called svchost is
consuming about 90-95% of the CPU Usage.

There have been improvements in svchost.exe over
the years, I am pretty sure.

Since you are also finding virus it is quite possible
you have more which are sleeping until the network
lights up and then running CPU usage up, but as you
say below, it might even be your ANTI-virus, your
automatic updates (or something along those lines),
or even offline storage of web pages....

This problem persists even after i go offline and even if i logoff and logon
again. Only when i restart the computer the CPU Usage gets back to normal.

I have a feeling that my anti virus has to do something with this but am not

It could be involved -- I stopped using Symantec
over similar issues, as it interferes with the proper
operation of the system far too often.
