Can someone please recommend a genuine free spyware blocker?

I am looking for a spy/adware blocker that a; really works, b; is really free and c; isn't a blind leader to other products. I use Norton (yawn...) regularly but now seem to have picked something up that when I go into Google, click on one of the many 'matches' and instead I get something completely different, ususlly a top 100 of something or other. I guess I could do with something to give my system a good 'clean up' too? (I do use Window washer). Any help gratefully received, Thanks.

I use SpywareBlaster, as well as Spybot and Ad-Aware SE.

They are all free, and seem to work well, with no technical problems.

They are all popular and widely recognised, so no fear of downloading spyware with them.
