About ,,'' will damage your computer

Hi,

last week my Mac started showing this weird message. Unfortunately I cant move the file to bin and also can't close the message.

I took Screenshots (which I've attached to this post) of the contents of my Finder Windows with the following names:

/Library/LaunchDaemons

/Library/LaunchAgents

~/Library/LaunchAgents

Maybe you can help me find the source causing this problem.

Thanks so much in advance.

Emily
