If you are using IE8 you can try http://www.neowin.net/news/main/09/04/02/ie8-ad-blocking-with-the-inprivate-filter Hostsman will also work http://www.abelhadigital.com/ Some suites like Outpost and KIS have an adfilter. There are also local proxy based solutions but I have not tried them. Maybe others can help.
