Damon Tools 4 includes adware searchbar (optional) - so don't install the searchbar if you don't like adware.
Use f.ex. Spybot:

- or Ad-Aware:
http://www.download.com/Ad-Aware-SE-...bj=dl&tag=top5
- or similar if you installed the searchbar and want to get rid of it
(...and other adware from your computer)!
