Redirect (search engines)

Hello.

I just noticed that when I use google, I don't see the drop down list of possible searches. That was the first problem I noticed, now when I go forward with the search and click on the link, I am directed to a different website. I am also noticing this with yahoo. I was not sure if this came from my son downloading firefox, which I have since deleted. I ran my malwarebytes & used super anti spyware, no luck. I would truly appreciate any advice.

Thank you.

I noticed a lot of people have this issue. Including me, everyone has fixed their issues by using Malwarebytes, Combofix, TDSSKiller, Hitman Pro 3-3.5 . You might want to try them yourself. ComboFix should only be run under the supervision of someone who has been trained in its use, as stated above.
