About once a day, Safari quits. A black screen comes up and then a "an error occurred while installing the extension "ManagerCore"" message. No idea what this extension is. I'm not set up to auto install or update extensions. Anyone heard of this?

Etrecheck – System Information 10.10 and later
Jacsrab - I dowloaded the Etrecheck app that Eric recommended above. It found some adware files that I got rid of per the instructions on the app. Had to delete some in safe mode, so they didn't re-install as soon as I moved them to the trash. It's been good for the last 5 days.
I too have the same problem!
Have you managed to solve it?
Thanks
Safari quits every day. "an error occurred while installing extension "ManagerCore"" message pops up. No idea what this is. Not set up to auto install extensions. How do I stop it?
