Are there any threads already on this subject? Keep getting this pop up stating 'Completer wants to make changes to your computer', and asking for my password. Google search states its malware affecting lots of macbook users. Im also getting an icon appear on my desktop called 'Installer'. Lots of folk reporting the free software AdwareMedic will find and remove the cause of the problem which is a Geneio file, but I haven't dared try it yet. Anyone else getting this problem?
