My web search started to work weirdly. It used to provide google search results, now it provides yahoo search results. by the way, they are deceptive! whenever I try to click on search outcomes, I can see a variety of links changing on the bottom left corner of my web browser, which, I believe, means that I am being redirected somewhere. Therefore, I always end up on very suspicious websites that I believe are infectious! Can you please explain what’s going on? And why search engine works like that?
