I have a macbook pro and when I type in a site like Twitter or Facebook the correct webpage would show up most of the time. But sometimes some random website that i didn't type at all shows up. Some other website i type in do this once in a while too but it's mostly twitter. Sometimes when i type in twitter.com some random blog site shows up and it's always the same one. Does my Mac have a virus or something ? If not then what's wrong with it ? :/
