This timely article appears the weekend I erase & install OSX having clicked the wrong download button on CyberDuck. The Google DoubleClick banner is prominent on the page, the actual software download is "below the fold". I should know better, but I clicked the big green "Download Now" next to the big Yellow duck, and underneath the same-Green Donate button. I ended-up downloading something wrapped in Genieo's InstallMac software, nothing to do with CyberDuck, who I wouldn't even mention except the banner is so prominent on the page. I also, dumbly, entered my admin credentials before aborting the install when it started downloading more components. Within seconds my search engine on all browsers was changed, start-page reset and other configuration including a process left running. The installed files and modified files were not easy to find, apple provide good help but it's hard to trust the computer once it's executed malicious deceptive code with root privilege. Clearly this was all my own fault and poor decision making.
