I wouldn't touch it with a bargepole, simply because anything that suddenly announces itself on your computer should be treated with extreme caution!
If you're getting messages about something that you've not already got on your computer, they're almost certainly being generated by malware. Download, install and run the
free version of Malwarebytes Anti-Malware:
https://www.malwarebytes.org/
(When installing it, take care to deselect the option to take a free trial of the 'Premium' version. When it finds malware, as it almost certainly will, select the 'Quarantine' option).
That should get rid of the messages you've been seeing.
