I visited " shorturl.at" after which the chrome notification popped up with "allow or block notifications" for this site.
I clicked allow, this then was followed by many notifications in the windows 10 notification area; with scam type links and messages indicating that "norton antivirus" was out of date etc. the links messages showed the "shorturl.at" url. When I did click on one, dummy windows for "windows defender" popped in a browser showing a scan and various virii being discovered, very much like when the conduit to bar was installed in the past.
I then blocked notifications in chrome, but they continued.
edited and reposted for clarity.
Desregard my mention of the link below because it isnt relevant.
