IE-SPYAD and ZonedOut

I have a question about IE-SPYAD for ZonedOut. I added the IE-SPYAD restricted sites to ZonedOut and was impressed with how many sites it blocked, but I am wondering if the "definition file" is something that has to be updated regularly. If it does, how often do updates to IE-SPYAD come out? Thanks!

I have given up on IE-SPYAD as it is not updated frequently enough.

SpywareBlaster and Spybot S&D's Immunize do a much better better job.

how often do updates to IE-SPYAD come out?
I have not seen any update regularity.

don't give up yet, IE-SPYAD is back in action, last updated april 17 2009(60000+ items)...

The IE-SPYAD Restricted zone list is regularly updated. You can download updated versions of IE-SPYAD from this very page, which lists the last time that IE-SPYAD was updated (see above and below). I usually try to update IE-SPYAD at least once a month, though I often update more frequently.

Looks like it's getting updated again.
