Why am I redirected to useless search sites when I click on a google search result?
Google is my home page, I search and get normal google results, when I then click on the site of choice, I am redirected to useless sites getting me to buy crap, for instance I google Air Canada, their official site is the first in the results, I click on it and am redirected to another search result page, this is the page http://www.informationgetter.com/search-results.aspx?keywords=air+canada
