Norton Internet Security - HTTP MS IIS NTLM ASN1 BO - Repeated alerts

Hi, does anybody know what this alert is about and how i can prevent them from being sent to me?

info from the security alert window:
Time: 17.59
Date: 27/03/2006
Intrusion: HTTP MS IIS NTLM ASN1 BO
Intruder: 172.143.61.173(1353) - had many different addresses will list more i have manually blocked below.
Risk Level: High
Protocol: TCP
Attacked IP: XXX.XXX.XX.XXX
Attacked Port: http(80).

Other addresses i have blocked include:
60.36.29.96(2117)
61.93.91.48
140.127.109.74
81.190.95.198

There are many more, they occur over different ports but i have recognised port 80 being used frequently. Im only asking here as the Symantec info page for HTTP MS IIS NTLM ASN1 BO found here: http://securityresponse.symantec.com/avcenter/nis_ids/s21141.html says that it could pose a serious threat and i have had a problem the other week to do with Veritas Net Backup or something and dont want it to repeat any help would be greatly appreciated.
I could use an answer to this problem as soon as possible as i am going away on the 29th March.

Thanks for reading, if you need anymore information please post and i will try to supply.

Update your computer with all the Windows Updates.
Make sure you have Norton's latest definition's.

Run msconfig from start -> run navigate to startup tab and uncheck everything you don't need starting up on your cpu.
Look in task manager for anything suspicious and try to keep those at a minimum as well.

Hi disrupt, thanks for your reply.

I have all windows updates and also nortons latest def's

I frequently check msconfig already for things that i dont want starting up, the only things that i have not unchecked in the list are things that look like they should be there when pc starts or things that i want to start up anyway like my webcam software etc.

As for things in task man' im not sure of everything so im going to list them and then maybe you can tell me if there is anything suspicious...

First of all I doubt your system is infected or so, because those alerts are
telling you that somebody keeps scanning your ports and trying to break in.

I would do the following:
send email to abuse@aol.net along with some logs which will prove that
you are telling the truth, and they will track the attacker down. If they
don't respond to you (I doubt this will happen), then come here again and
You'll be given the email of the AOL's upstream provider, so you can try
contacting them instead of AOL.


Anyway, if you want to check your computer, you can do it with HijackThis,
and upload your log at www.hijackthis.de, and post the link to the uploaded
log here, for further assistance, to make sure your system is clear.

Hi nepostojeci email,

Thanks for your response. I have noticed in the past day that the frequency of these attacks has slowed somewhat but i have increased the amount of time that attackers are blocked for from Norton Firewall controls. They are however still coming in so i will follow your suggested course of action by contacting AOL with my logs. I will however need to wait for the logs to accumulate as they are wiped every time i shut pc down.

As for my HJthis log i will paste it below...

I would not be too concerned about this.  I think that your firewall software defaults are doing what they are supposed to be doing.  Any slowness is because you are running so many background services cause by Norton itself.   The typicall intruder detection could also be cause by listening daemons broadcasting listening requests.  Most firewall software will show these types of activities.  You should chalk this up as nothing.
