I recently took a couple of trips across the US on Greyhound. On the trip back to CA I used my own hotspot while on Greyhound. The result was having my Avast Anti-Virus (free version) hacked by Icomera (the provider of Greyhound FREE wi-fi) ....
The HACK was on the EMAIL GUARD in Avast Anti-Virus.
The hack involved insertion of 1) html pages 2) "DLL" files ...
I have attached images of the file(s) inserted on 09/27/18 and the insertion of a "NOTE" at the end of my emails advertising Greyhound's FREE Wi-Fi with active links to ICOMERA.
This should raise red flags immediately!!!
Thanks,
Forrest
