Today I noticed that every time I do a search on google, yahoo, or any search engine for that matter, and when i click a link i get redirected, for example: i open mozilla firefox and i start a search for super smash brothers; the links come up but if i click on them they all redirect to random sites that have nothing to do with what i was looking for. my nephew used my computer this past weekend and i bet he got something off a site or downloading something that got this issue. whats wrong with my search engines and is there a way to fix it or would i need more info for you guys to know what im talking about?
