HELP ! HP System Restore, Internet not working

I recently had a new motherboard and hard drive installed in my HP Pavilion 310n. After succesfully loading the 6 disc HP XP Recovery discs, which I purchased 2 months ago from HP, I connected to the internet to register the new installation. Right away, my system slowed down alot, the Internet Explorer browser just kept 'searching' for the microsoft site, and finally the "System is shutting down....initialized by the NT Authority/System....C:\WINDOWS\SYSTEM32\ISASS.EXE...will terminate unexpectedly..code# 107374189" window popped-up.

This is the 3rd time this has happened to me while installing a new XP operating system on 3 different PC's! 2 on Dells (with Dell XP installations) and now on my HP (with an HP XP installation).

2 things:

1. Why is this happening? Are the drivers corrupted?

2. How can I fix the problem?

I loaded Norton Professional, updated it (in safe mode, the only way the internet works), and ran it deleted a couple of viruses. I also downloaded and ran VGS, which also found some viruses. backdoor.bot was one of them.

HELP!!!

Welcome to WD.
You have a virus/worm. Does it tell you it is going to shut down in 15 minutes?
You need to enable the firewall before you even go online to take care of this. So, from now on, don't register or activate upon boot up, but instead skip it and say you want to be reminded. In the meantime, I'll find the link for you.
It is either MS Blaster worm or Welchia.


Here is a link about the variants:

Thanks for the help.

The message that comes up says it will shut down in60 seconds. However, it doesn't do it every single time. Instead, the internet just stops working. i notice in the back, that the ethernet light just keeps blinking really fast, but the page doesn't load.

Where do I enable the firewall?

Yeah, I didn't mean 15 minutes. It's been awhile since I've seen those problems. :)
Right click on My Network Places and choose Properties.
When Network Properties window opens, right click on your net connection and choose properties again and then go to advanced. There it is: check it off.
Which version of XP is this?
Here is another d/l which takes care of some malicious worms, etc.

You may look at that security section of MS and read up if you do this alot.

It is XP Home.

I downloaded the Malicious Software check patch from microsoft. i ran it and said my pc was not infected. Problem still exists.


Any other ideas?

I'm picking up the worm Optix Pro from tha isaas.exe file.
But that worm doesn't do what you said in post 1. Also, how did you update you NAV in safe mode?
Anyway, is NAV updated?
Are you still getting knocked off the internet after 60 seconds?
If Nav is updated then boot up in safe mode and run Norton. Something is funny about this though, that worm is supposed to disable virus and f/w proggies:

And, it's pretty old.
You may have to give us a HiJack this log because you seem to have multiple issues.
