On a Windows 10 last version 2H2 (10.0.19043.1237) Kaspersky Internet Security (ver the MAST installer gaves an error saying is a trojan, then is bocked by antivirus.

The workaroud is to disable the antivirus and put the exe in the exclusion list.

Scanned the exe file in various antiviruses and there is no infeccion.

This put us in a bad position when we are installing the backup software on our customers networks.

This failure was reported a few years ago, and it seems that it has camed back.

Please  look after this matter ASAP.


Many thanks
