Laptop, Amilo Pro, operating Windows XP Pro SP2

After the automatic windows update downloaded some security updates from the MS update site, the laptop in question behaved very strange.

1. The internet connection is disabled, and cannot connect.
2. The network connections icon is missing from control panel.
3. The user accounts icon is missing from the control panel
4. The firewall icon is missing from control panel
5. The ad and remove programs icon is missing from control panel.

There may be some other icons also missing, but above are the once I was looking for to see if I could solve this issue.

The laptop keep on getting a pop up messages saying: "Bad ImageThe application dll c:\WINNT\System32\ATL.DLL is not a valid Windows image. Please check this against your installation"

I copied the atl.dll file from my healthy computer over to the laptop system32 folder, overwriting the existing one, and it seems to solve the atl.dll bad image problem. Network connections icon were back in cpanel as wel, but nothing happens when I try to open it.

I cannot run any commands from the start menu > run and the only way I can get the run function is by cntrl alt delete and then new task and run from there.

From above command line, I tried to run sfc /scannow. The little scan window opened, but nothing happend, no movement in it.

I also ran a scan disk, rebooted, and a lot of files and stuff were deleted and replaced, but still, it did not solve anything.

My next step was to try and do a restore. I booted up in safe mode, and tried to restore to a date before the update, but after the laptop boots up again when restore was completed, the restore window comes up to say that it could not restore to that date.

I then downloaded to a removable disk on my healthy pc malwarebites, and install it on the laptop, run it, but it found nothing.

Now I downloaded HJT via my healthy computer, and installed and run it on the laptop. The log follows below.

Please, if there is some Daniweb family member that can help me with this one?

Here is the HJT Log:
