Installation of .Net Framework v1.1.4322 disables Standby Mode

I have an XP Home system (Dell Inspiron B130 laptop), SP2 fully patched
through last month.I ran the July patches last night (went to Microsoft
Update and selected Express). According to MS, the only updates I needed were
the Malware Removal Tool (KB 890830), the .Net Framework (KB928366), and an
XP update (KB 936357). I also ran the Root Certificate update.

All seemed to install without difficulty. I did the reboot requested. Logged
back in Microsoft Update which showed all patches successfully installed
(confirmed under Add/Remove Programs). I turned the system off.

This morning after working with the system, I tried to put the machine into
Standy, only to get the following message:

Service .Net Framework v 1.1.4322 Update is preventing the machine from
entering standby. try stopping this service and try again.

Thinking that perhaps the issue was that the patching had been done under my
admin profile, while Internet browsing this morn had been under my normal
user profile, and that I had not tried entering standby as an admin, I shut
down and rebooted under my admin profile. Trying to Standby, I received the
same message.

I welcome any suggestions as to how I might fix this problem.

You're mowst welcome. And, I certainly understand why you are reluctant
to disable the AV while online.

Let's skip to the crux of the matter ... make sure that the Net
Framework v1.1.4322 update Service is no longer listed in Services in
the System Configuration Utility.
If it is not, then perhaps AntiVir has included a fix in their latest
update.
Since the system is no longer having a Standby issue, then that is a
possibility.

At this point it would be best to confirm that the update has installed:

Under 'Update Information' click the plus sign next to
Security Update Deployment
Click the plus sign next to Microsoft .NET Framework 1.1
Check the ' Registry Key Verification ' information and compare it to
your system
Below that is 'File Information '
Compare the file versions of the specific KB that was installed against
the ones on the system.

If you need to redownload the update, the above Security bulletin page
has links to the MS Download Center for the KB that is needed.
I certainly hope that the update is now successfully installed and that
you don't have to take that route.

I am a total amateur compared to the rest of you, but having the same aggravating problem with the update.
How do I fix it?
