The rogue "Installer" program is a consequence of installing adware. You do not need to download or install anything to fix it. Removing it requires a methodical approach because its name is always changing.

Navigate to the following folder, and post its contents in a screenshot.

~/Library/LaunchAgents

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. It should look like this:

Take a screenshot showing all that folder's contents, and post it in a reply. To take a screenshot read the Appendix in the following User Tip: Writing an effective Apple Support Communities question.

There will be additional instructions to follow.

For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware.

Review your Gatekeeper settings: OS X : About Gatekeeper - Apple Support. Gatekeeper is designed to help prevent you from inadvertently installing garbage software.

How do I trash and what do I trash?

I was just about to download Sophos to sort it out.

I definitely don't have either of those apps.

So what do I need to do? Find those items and delete them? Are these them?

Hi, thanks for this, I deleted one dodgy file from that folder, here's what's left in it.

MACJACK,

How do I set the security to the App Store only as you suggested?

Keep your security set to “App Store and identified developers”

Thanks,

Dave

I had the same problem. I spent hours trying to delete this stuff. You have adware on your mac which needs to be removed. I went to the following site and downloaded this software and it worked a treat. https://www.malwarebytes.com/

I followed Dave's advice, after asking my daughter if it was OK and checking it out on Google, and I have to say, this malware download worked great for my problem. I had downloaded an update to flashplayer and it came with an adware program that I figured was a scam. It also caused some of my e-mails to certain internet servers to come back as "undeliverable." After I downloaded the malware, all my problems disappeared. From now on, I'm going to Adobe's website to install updates and hope that they are safe.

I've read the responses and I don't have any of the stuff on my MAC. How do I remove this from my MAC?
