Ad blocking Extension/Addon for IE7?

Does anyone know of a good ad-blocking extension for IE7 - like Ad Block Plus (& Ad Block Filter Set..) for Firefox? Likewise, one that interferes with click tracking etc, etc in Google - like Customizegoogle for Firefox?

I'm fairly certain those are trustworthy, not rogue. I'm far less certain about stuff I see on 'Manage Addons' in IE7...

Edit - OK - discovered IE7pro. Hope it's not rogue... But I'll give it a try...
Edit again: Brilliant! Try the CCleaner update link to www.ccleaner.com: gets rid of the nasties and also the 'ads by Google'

 

Thanks Steve - yes, I knew all about that... I thought everyone did. I was looking for something a little more sophisticated. As you know, pop-up blockers only block, er, pop-ups. Anyhow, I do think I've found what I'm looking for - though I'll need to check it out for privacy/security issues. Some of the stuff 'recommended' in IE7 'manage add-ons' is - well, let's just say, worth checking out for security and privacy issues...
