Laptop with Windows 10 and Norton Internet Security v 22.9.1.12 Decided to check quarantine folder just to get an idea of thing. Noticed that a file was quarantined 3/25/17. The file is directionsandmaps. exe ( I spaced the dot exe part for safety). It flagged this file as- Threat Heur.AdvML.B and it indicated that the file was rather new. So I looked back in history and found that on 3/25/17 my wife had gone to the website proinstall-download. com ( again I spaced the dot com part for safety here). So when I look in the download insight category of my Norton history, it shows that Norton did not block access to this website or block any downloading from the website. I do see that a few minutes later, it did quarantine the exe file I noted above. So questions become- Is this file a Trojan as descriptions of Heur.AdvML.B found on google seem to indicate ( or is it a false positive)? Why didn’t the Norton block access to the file to start? Since the file was downloaded before being quarantined, does that now open my laptop up to maliciousness from this file or stop it before anything bad could happen??
