Hello, McW5001.
Thank you for using Apple Support Communities.
From your post, it's understood you were able to remove Search Marquis from Safari but not from Google Chrome. We'd be glad to help. Open Chrome, then go to the three dots in the corner of Chrome, and click on Settings. Then go to Advanced and click on Reset Settings. Note, you should see a pop up explaining what the reset will do. After the reset, close the app and open it back up to see if the issue persists.
You can confirm if Malwarebytes was able to remove anything related to this malware by following these steps:
Look for any suspicious files here:
- /Library/LaunchAgents/
- /Library/LaunchDaemons/
- ~/Library/LaunchAgents/
If you see this, "com.gregorian.gettime.plist", remove it.
In addition, follow these steps and remove anything related to gettime malware:
- Navigate to the ~/Library/Application Support/ folder in Finder.
- Use the keyboard shortcut Command+Shift+Period to reveal hidden items.
- Move the folder named '.gettime' to the Trash.
- Use the keyboard shortcut Command+Shift+Period to hide hidden items.
- Note: If using 'ABC - AZERTY' keyboard layout, use Command+Shift+Fn+Period.
- Restart the computer.
Keep us updated.
Cheers!
