I think it happens every time Firefox gets updated. I find a yahoo.com Add-on, and a couple of other commercial services installed. The worse thing is, the Yahoo add-0n takes over my Mac! If I try to access a page, the Add-on diverts me to the Yahoo search page and gives me an Error -404, page not found msg!

Ok, I delete them and restart Firefox but even though I have the Avast Online Security active, it has never stopped these menaces. Where do they come from? Is my Browser compromised?

BTW, I'm running Avast 9.0 on OSX 10.9.4 (21inch intel imac)
