I installed the trial version of Scanguard a few days ago, Today, I uninstalled it, but it left an artifact inside “System Settings → General → Login items.”
How do I get rid of it?
You can use iBoysoft Cleaner to clean the residual file. (Open it, then click System Junk to scan for junk files. After the scan is complete, click Uninstalled Residual Apps to delete files related to the app.)
Or, if you haven’t emptied the Trash, you can put it back and then use this tool to completely uninstall it.
Restart your Mac after uninstalling the app.
