Guys/Gals, how effective are "white listing" security apps?

By "white listing" apps I mean stuff like Exe lockdown :

How effective are they really? A few questions I have are :
What if I'm visiting a website that attempts a "drive-by" download?
What about stuff like SONY DRM rootkits that attempt to install from a CD/DVD?
What about things that are not exe's but run if you click them like .reg files or scripts?

thanks for the link. it seems that these things (white listing apps) are incredibly useful. one last question remains though. how are they vs non executables? what happens if you click a .reg file or a script (like .js)? or are those counted as executables?

 

I think that scripts are counted as executables. Ask Rmus (he´s the guy who made the tests in the link posted above) about this.
Needless to say, pure whitelisting apps. are good for static systems.

 

Hmmm, Linkscanner Pro didn't like that link.
