I downloaded the VLC program and with it the annoying Chatzum toolbar which now appears each time I run Safari.
That will teach me to be more careful in future!
How do I remove this from my mac?
When going through the uninstall procedure, an error message appears stopping me from completing the process.
Help would be very much appreciated.
