Q: I just got this on my desktop : Please run InstallMac compatibility test and updates for the upcoming Mac OSX. I have to agree to set my search to Leperdvil.

It's a scam, ignore it.

InstallMac is malware but AdwareMedic can remove it. It's a scam.

Download and run AdwareMedic

You're welcome

Leperdvil and InstallMac are alternate names for the Genieo adware.

I'm unclear on whether you have it installed or are seeing a reference to it within an installer you were running. If the former, you can check your system with Malwarebytes Anti-Malware for Mac (which used to be AdwareMedic, the product Carolyn recommended). It will remove the Leperdvil variant of Genieo.

If the latter, quit the installer immediately! If it won't quit, press command-option-esc and then force quit the installer. You still may potentially have some components of adware installed, so it would still be wise to check for any adware.

Glad I could help!

Hi There,

I think I have a similar issue. My idiot son has tried downloading something (seems to think some kind of viewer which i have stuckl to the TRASH and emptied now) which has now resulted in my safari home page  as leperdevil etc etc. From what you have said above this sounds bad !!! I did try the Maiware bytes as mentioned but the problem still persists. Any tips or help ???

Regards from a worried MAC user

PS Son available ???

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. You can link to this one.

Manual method:

Malware – Adware removal – Apple Support

Or download this program which was written by Thomas Reed, a long time poster. The program will do the work for you which makes it easy. If you are uncertain about downloading programs, try the manual method.

Malwarebytes Anti-Malware for Mac      10.7 and later

You should be aware that removing the Genieo (aka Leperdvil) adware with Malwarebytes Anti-Malware for Mac does not re-set your browser's home page and search engine settings. You still have to do that manually. See:

How can I reset my browser's home page and search settings on Mac?

(Fair disclosure: I am affiliated with Malwarebytes.)

I download AdwareMedic but am being told I cannot use it since I'm running OS 10.75 and it requires OS 10.8. Other than the obvious upgrade, is there another software that will rout out the 'devil' and get it off my system?

See the manual method in my last post.

You can download a version of Malwarebytes Anti-Malware for Mac that works on 10.7 here:
