I recently noticed something on firrfox, something is trying to redirect me to another page called setch.avazutracking.net. Is it a virus beacause mfafee can't detect it and I need to delete it really quickly.

I want you to reset firefox back to defaults, to do this I need you to do this
I moved this to the Malware Discussion area but not sure if it's really malware. Try running Stinger and Malwarebytes Free both found in the last link in my signature below as a precaution.
