While you're statement is entirely true, I believe what Daniel is
trying to point out is the fact that NAV's script blocking feature
(which is supposed to stop ALL attacks, known or not, if they involve
scripting) isn't working.

If you don't password protect your AV settings, a simple batch file
can disable many of them (NAV included) by mimicing their uninstall
routines. A VB script should be stopped by the built in script
blocking, making a more complicated script (as compared to a few-line
batch file) impossible to wreak havoc on your system, or to the AV
program itself.

Though I haven't tested Daniel's script itself, if what he states is
true, then there is certainly a problem with the script based
protection.
