Security Software Conflicts with AJAX?

ithyus needs help with the following: "My employer is running an e-commerce site that, until recently, our customers were quite happy to use. With increased traffic to the site we decided to implement AJAX to try to reduce the load on our database servers. In doing so, our customers have experienced all kinds of problems with security/privacy software such as Norton and McAfee. It seems that no matter what we do we can't make these programs happy. Bigger companies such as Google have documented work arounds for some of them, but we wouldn't be able to keep our docs current with all the software that's presently out there. I'd really like to know how Slashdot's readers have handled these issues. Since security programs don't appear to be compatible with the emerging features of the Internet, do you simply suggest that the customer disable the offending software or do you opt to offer some support for the more popular ones? Are those really the only two options? How do you justify your method?"

Re:what are the specific problems?

With security like that, your stuff is so amazingly gone.

You're telling me that IE's XHR violates the HTTP protocol? I'm shocked, sir!
