No one buiding websites performs such testing on a regular basis like we do here, but one can easily imagine how scripts are being run, vulnerable to shellcode attacks and XSS exploits, in that case the reason to retire such script versions and retirable script is obvious:
For understanding
cl.write & inner HTML & b.value.a
exploitation, read here: htxp://howcanfix.com/28955/help-me-understand-this-javascript-exploit.
Would be a nice example to be used by TINSEC students as a test case to solve insecurity aspects (test in jslint & jsunpack), and for us here to get further protection against, also is important in general browser protection.
Remember when testing * I first got an unresponsive browser (latest flaw of Iridium, and then it collapsed), so be aware where Shellcode and Javascript can have it’s evil ways.

Hi -midnight,
Do not panick, the webshield alerted, but you were never really in danger. I would not dare.
Avast alerted here because it found parts of real code (the code in my example is harmless,
but the webshield cannot discriminate between this and the real McCoy).
Well I have broken the link for those that would not understand the alert after clicking that link (meant for code analyzers actually).
You haven’t run any risk whatsoever, but it proves if it had been used in real malicious code, the webshield would have saved you.

Hi polonus,
I click on a lot of your links. I didn’t panic but kind of scared me. I didn’t know that it was meant for code analyzers.
-midnight
Hi -midnight,
You absolutely did not run any risks whatsoever in this instance.
The webshield was just barking up a tree, but there was no tree in sight (no real payload there).
It was just some part of the code that made it show that message and blocking it for you.
So you were secure all the way from the word go and clicking the link.
Remember not to click any links I give in my postings that I have broken,
that means -http(s) or hxtp or hxtps.
