Safe Finder

Did you try running Malwarebytes, it would be more up to date than the article.

Other suggestion...

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

I am a technician at a computer repair store. There is very little helpful information on the internet about this. I find that it doesn't appear as an extension in Safari, but I have found a work around that seems to be working consistently for me when I see a unit that has this issue. A little warning, this process doesn't appear to log you out of any websites, but you may lose any extensions that you installed and other settings may be reset to default values.

1) Open Safari and change your homepage and search engine options in the preferences window. If Safe Finder doesn't allow these changes to be made, try this step after performing step 2.

2) Open finder, click "Go" at the top of the screen and hold the "Option" key. Select "Library". Scroll down and locate the "Safari" and "SafariSafeBrowsing" folders. Drag and drop these to the desktop or directly to the trash can (Don't delete them just yet). Quit Safari and restart your Mac. Open Safari and do a test search in the URL box and it should bring up a result using your preferred search engine with no Safe Finder logo or ads in sight. Place the folders you moved to the desktop into the trash can and empty your trash can

3) Perform step 1 if you previously couldn't

Hope this works for you like it has been for me!

Hello,

Malwarebytes…

Did you mistakenly mark it solved?

If so there's no way to undo it, I'd start a new topic to get other help.
