The NIS 2008 Phishing Protection is freezing some pages on our business website.
I am not going to publicly post the addresses as I don’t want anyone to think I am looking for “free advertising”.
When I go to view the pages in question, they start to load and then just freeze – so badly that I have to escape IE7 with task manger.
1) This did not occur with NIS 2007.
2) If I turn off NIS 2008 Phishing, the page loads fine.
3) If I then turn on IE7 Phishing Filter, the page loads fine.
4) If I try Firefox 2 with NIS 2008 Phishing ON, the page loads fine.
5) I do not run IE7 Phishing at the same time as NIS.
6) I ran the Symantec Auto-check tool; no problems
7) Live Update was just run and everything is up to date.
8) There have been no changes to the page html code.
The problem is that we received a few phone calls yesterday from prospective customers who could not access the pages. At the time, we did not think to ask if they were running NIS. It was only when we tried to access the pages did we discover the problem.
This has occurred on two separate computers, both running XP SP2 and both running NIS 2008 version 15.5.0.23. NIS 2008 was just recently installed over NIS 2007.
Interesting note: We have one computer running Vista SP1 which as of yet has not exhibited this problem. It also has NIS 2008 v 15.5.0.23.
I did submit this issue to Symantec via email approximately 14 hours ago, but as you can understand we are rather concerned.
Although there has been no activity on this topic, I thought I’d post the solution I found, hoping that it may assist someone else in the future.
First, although I have been an avid supporter of Norton Products for years, I am disappointed that my email has gone unanswered.
In analyzing when the pages were freezing, I noted that they would hang while trying to download the PayPal “Buy Now” button image from the PayPal website.
I decided to download the button image from the PayPal site and place it on my local site. In Dreamweaver, I simply changed the button image source from PayPal.com to my local site, leaving all the links and encryption to PayPal undisturbed.
I turned the NIS 2008 Phishing Protection back on and no problems – the pages load just as they did before.
However, I’m still curious to know why NIS 2008 Phishing in IE7 on two XP SP2 machines was causing these pages to hang, while the other filter and browser combinations mentioned in my first post had no problems. Also, it never occurred with NIS 2007.
Someone may respond that the problem was with our web pages, but the web pages in question have been up for years (updated from time to time, but not recently) and we always perform cross-browser checking on various platforms including Macs to ensure world-wide compatibility. This was the first time we encountered an issue.
I’m still happy with the Norton product line and certainly won’t leave them over this.
