hi Teresa, sorry for the issues you are having - just as a general not i want to say that no mal- or adware will ever come bundled with a genuine firefox update. there are some pages which show bogus update notifications which want to trick users into downloading unnecessary stuff - however, updates are handled automatically and internally by firefox so you don't have to download anything manually and can ignore such popups (you can initiate a check for updates in the firefox ''menu ≡ > help ? > about firefox''). in order to resolve the issue please perform all these steps: # [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords) # afterwards go to the firefox menu ≡ > addons > extensions and in case there are still extensions listed there, disable them. # finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.
