well, they both block scripts launched from websites.
I have "ZA pro 4 with webfiltering" and also use the script blocking from zone alarm, aswell the script blocker from AVAST 4.0 Pro.
I have
no problems viewing websites under these settings.
I guess maybe its a little overkill, but as long as they don't interfier wich each other, why not run both.
They serve the same purpose, but what the heck, having a layered defense is always better...
Btw : congrats on buying the best AV ever (atleast better than NAV)
