I have Norton Internet Security 2000. There is a way to do ad blocking but it unfortunately works only on pop-up ads. The rest will still open. It has decreased the amount I have to look at though. Also, if you disable java scripts in your internet security settings you will do away with alot. Just go to Internet settings and select custom, from there you will be able to find java scripts and just turn it off. This may not be the best way but its one I know of.
