Hello, I wanted to ask for help. I did something wrong and now my browser opens Mediafiretrend.com search engine when I open new tab or just simply open my web browser. What is the reason? Why is this happening? I tried to search for some movies using this search engine, however, I was really disappointed and besides I also received some annoying pop-up ads asking me to install some never-heard-of computer cleaners, which look like viruses to me. Why do I see Mediafiretrend.com every time I open my browser and how can I get rid of it? Also, how should I block these ads?
