Every time I browse something it would take me to Yahoo Mexico
Every time I browse something, anything, instead of taking me to Google it would take me to Yahoo Mexico, and I'm not even Mexican or at Mexico. It's supposed to take me to https://www.google.com.ar/?client=safari. I think I have dowloaded a small malware or something, and I have read some things about checking my extensions but the thing is, I've got none.
Also I prefer using Safari, rather than installing Google again due to some inconveniences in the past.
Please, help me!
