online stores/ads in search results

[raverx3m]

ok i have notticed recently that theres more and more useless ads adn online stores and all kinds of businesses coming up in search results
for example i search for antec sp-400 repair and it gives me 2 full pages of online stores and no results for actual repair because i ve searched for it before and found it but cant find it again

so heres my question:
is there a way to block the adresses like: newegg amazon,ebay, bestbuy,compusa and basically most online stores that offer products because its really faquin annoying to have to browse thru tonns of unrelated crap that pops up in order to fidn somehting you looking for.

or is there an alternative search method or webpage or even a programm i can use?

Only if you know the URL where the advisement are coming from. If you block those from being resolved through your HOST file.
