pleeease help me. The arrow won't go away.
Hmmm, if there's no application to uninstall, lets try to delete the files:
Go to Finder, press
Command, Shift and G at the same time, and then enter the following addresses in the Go to Folder box.
Go to these folders and delete the suspicious files.
/Library/LaunchAgents
-- search for suspicious files and move them to the Trash. There should be a few strings related to 1ClickPDF.
/Library/Application Support
-- search for 1ClickPDF and move it to the Trash.
~/Library/LaunchAgents
-- search for suspicious files and move them to the Trash. There should be a few strings related to 1ClickPDF.
/Library/LaunchDaemons
-- search for 1ClickPDF and move it to the Trash.
~/Library/Safari/Extensions/
-- search for 1ClickPDF and move it to the Trash.
Restart the computer and check if the issue is solved.
