Completer wants to make changes. Type in your password to allow this. I have never seen this before and it wants my admin. pw.

Question

I've never seen this request before.  I rarely shut down my computer, and when I restarted it this morning, the above is what I got in a small box.  I've tried to find "Completer" in help and communities but there is nothing.  I don't want to put in my password until I know it is valid.   I found on "google search" about Genieno which led me to a link in the Apple Communities.  There is nothing in my apps or computer with that name.  Anybody know what this is?  Thanks.

Answer 1

There should be nothing native to the OS X which would ask for a password
or  other information on a restart, unless accompanied by the traditional login
box with your user name.
There are adware or marginal products that could be called malware (bad)
that would impose their presence and some items that could have been
downloaded by accident or through some corrupted free software site; of
those some could ask for and gain permission to go through your Mac
and maybe even run in the background to do other nefarious misdeeds.
You could see if startup in SafeBoot allows you access past that the Completer.
Since I don't have a pile of helpful article links on how to resolve various issues
I'd be looking them up one way or another.
There are some helpful items in the site http://thesafemac.com - see Tech Guides
listed  (adware, malware, & performance) plus a link to the adwaremedic page.
Also, Apple support has a helpful page on how to remove adware and other bits:
•Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support
Hopefully this helps somewhat.
Good luck & happy computing!
