Windows is shutting down

J

John

While operating in Windows XP, windows will suddenly
shut down on its own without warning. The
message 'windows is shutting down' appears and then shuts
down. This can happen anywhere from five minutes to an
hour after starting windows. This always happens while
connected to the internet.

Any thoughts?????

You probably have Blaster or a variant. This means you don't have your
firewall
enabled, or use another good firewall - and haven't run Windows Update
regularly to get all critical patches (the fixes for this came out during
the summer of '03). You need be connected for only a few seconds in order to
get infected!

See http://www.visualante.org/msblast/main.htm for lots of good
info....and/or follow the instructions below.

If you can't stop your computer from restarting:

As soon as your computer reboots and Windows loads, click Start, then Run.
In the box, type the following:

shutdown -a (then click OK)

Install:

http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/bulletin/MS03-026.asp
As soon as you can!. You are running the 32-bit edition of Windows XP, btw;
you'd know if you weren't, trust me.


If you get
setup could not verify the integrity of the file
/ cryptographic services message, see
http://support.microsoft.com/?scid=kb;en-us;326815 (for XP) or
http://support.microsoft.com/?id=281458 (for Win2k)

For the removal tool for the MSBlast worm see
http://securityresponse.symantec.com/avcenter/venc/data/w32.blaster.worm.removal.tool.html.
Note - this is not the only worm/exploit out there - it just seems to be the
most common one.

Get a firewall! You NEED one. There are several free ones, including
Sygate ( www.sygate.com )

Then go to WindowsUpdate to pick up the latest updates:
http://windowsupdate.microsoft.com. (You should do this about once a month
anyway, at least)

More info about the worm:
http://securityresponse.symantec.com/avcenter/venc/data/w32.blaster.worm.html
and http://support.microsoft.com/?scid=kb;en-us;823980

You also need good antivirus software - for personal use, AVG 6.0 is free -
www.grisoft.com - set it to update daily.

I've found the problem I have had the same on my
machine. Its svchost, a generic file which is draining
all cpu and memory available ,almost and causes the
shutdown. Although I've found how to put it right and I
can't see a way of not costing. If you have since you
posted this please please let me know, thanks

SVChost is an essential component of the system that provides the
interface to a whole slew of services - and the system will not run
without some of them. You have to identify *which* of the services it
is that has run away. It may well be an intrusive piece of spyware -
run Adaware from www.lavasoftusa.com to track down and remove these
things.

You can go to Control Panel - Admin tools - services, and with Task
Manager running to show effects, cautiously select and Stop services
that show as 'Started'. Check on what each does to make sure it does
not look critical, and if there is no effect, start it again

If you identify one, double click on it and set Startup type to Manual
rather than Disabled in the first instance. Ones you can reasonably
safely Stop on a stand alone machine (or probably non-corporate LAN )
are

Background Intelligent transfer (though it is used by Auto Update,
manual update works fine without)
Routing and remote access
Both of which seem implicated in heavy usage of CPU

SSDP Discovery and
U PnP
provided you don't need it for a UPnP router

Alerter (which is *not* needed for error alerts on the local machine)

Indexing (unless the use of context in searches is an actual benefit)

IMAPI CD Burning (if third party CD burning is implemented or you have
no CD writer)

Messenger (against the pop-up ads, though of course NetBIOS should be
blocked in a firewall, this is better than nothing - and is doing no
good in the sort of setups mentioned)

QoS RSVP (not that it causes the trouble that street wisdom suggests -
but it doesn't do anything positive)
