hi soda.. glad you're all fixed up.. CoolWebSearch is one of the worst hijackers there is..
as seen by this link.. http://www.spywareinfo.com/~merijn/cwschronicles.html CWS, is always changing "it's spots" so as a result, one should always download the latest version and not trust only the version you have attached.. so, just to make your thread a bit more complete, I'll give two direct download links.. one an exe file, the other a zip.
