Just watch what you install. I don't think anything is as good as being careful at the end of the day these type of things are normally installed with free software so read each step as you are installing things and review what your about to install by using a simple google search on it to reveal any of it's hidden dark sides. So you are the best tool to be honest.
You could try avast they claim to have a good antihijack tool built into the antivirus
From memory I think Malwarebytes antimalware also blocks on installation some of these things but only the full version will do it real time.
You are the best defence being vigilant and reviewing what you install before you do so. A little effort can often save a lot of pain.
A good tool to use if you do get something browser related is junk ware remover
MVP Hosts blocks some hijackers from conecting but will need to be checked from time to time for updates
