Why update firefox and got a 'free' bing search bar and two software malicious adware?

After an automatic update - no, I do not download no matter what new version of any dangerous place - I found that I had the Bing search bar-which I think I've turned it off, not sure if - and two malware/adware problems. First was rvzr - a.akamaihd which arises a new tab when clicking first on a website, then I found that I had offerswizard adding banners - blocked most of them - and the creation of hiperlinks with mini pop ups when passed above it with the mouse - sorry if my English is not clear. I tried AVG free and there wasn't any warning. Finally, ad-block and rgiht, click on the arrow to search bing seems to fix the problem, however, offerswizard must be uninstalled manually - lightning enhance program, I think that - after a google search.
The main question is... can I trust firefox download/upgrade to automatic update?

Thank you all for your answers. I tried to mark it as resolved, but I doubt that I did.

First I tried in windows / removal of unwanted software programs. Installed an adblocker for FF
Then I downloaded the adware 3.8 removal tool and the problem is almost solved. Still a few details could be improved, but I can live with that.

I think someone took advantage of the installation of FF and it makes any other malware on my computer.

Thank you once again.
