How to stop softfonic notifications

For some reason I get multiple times a day a softonic notification on the top right hand corner of my Mac's screen. I have not installed softonic and there is not softonic notifications under system preferecences>notifications.

Malware bytes does not report any malware.

Does anyone have an idea how to remove softonic and get rid of this é"'&é"§&é!è"(@& company and malware?

thanks
