On the wife’s computer the avast Webshield blocked access to t.hanstrack. com because of BV:Miner-T[Trj].
I scanned here and here without any threat result: https://www.virustotal.com/#/domain/t.hanstracker.com
and https://www.virustotal.com/#/domain/ww7.hanstracker.com
Also consider: http://portalsranks.stream/domain-page/hanstrackr.com
Is that alert still actual or has it been taken down already?
See script and page has been moved: https://aw-snap.info/file-viewer/?protocol=not-secure&tgt=t.hanstracker.com&ref_sel=GSP2&ua_sel=ff&fs=1
