Question : Norton Internet Worm Protection has detected and blocked an intrusion attempt.

Here are the details:

    Intrusion : Portscan.
    Intruder : 192.168.0.1(domain(53)).
    Risk level : medium
    Protocol : UDP
    Attacked IP : USER-COMPUTER(192.168.0.100)
    Attacked port : 1170
 
When I received this alert, Norton (I think) blocks all communication. The only remedy that I have found is to turn off the computer and restart!

I know that when I receive this notice at another client's computer. I discovered that the Internet Worm Protection | Autoblock rules were not turned on.

In this case Internet Worm Protection | Autoblock rules are turned on. I have done several searches and I have found anything really interesting. Any assistance is greatly appreciated!

The computer in question is using XP SP2 with a D-Link router DI-604

Thanks!

(Yet another user complaining about how Norton has broken their computer.)

I'm pretty sure that 50-60% of headaches that people complain about are caused by bad antivirus packages like Symantec/Norton.
Mac OS X works so much better because it isn't clogged full of junk applications that really stop nothing.

Enough Symantec bashing. =)
