I am trying to completely uninstall AVG Linkscanner version 9.0 from my new mac. I deleted the app a long time ago, but the menubar icon remains and still opens up unwanted notifications. Can I get an uninstaller for this? I know there must be junk files I need to get rid of to fix this, but I don't know where they are. Any help is greatly appreciated!

You are most welcome Isabel.
