Hi, the same thing happened to me too.
Update proposed by the app with the usual screen that warned of the presence of an update and asked what to do.
Already during the installation the warning went off.
Application: Fences6_setup.exe - Type: Trojan - Name: PDM:Trojan.Win32.Generic
Immediately after involving other different files, always from Fences6, such as FencesMenu64.dll
(Win 11 Pro and Kaspersky Premium 21.20.8.505)
In the end it did not even allow me the classic uninstallation.
I manually downloaded a new installation file from the official source, but once again...
I could only perform the manual uninstallation and now I am without Fences.
I have been using Fences for many years, but I cannot risk it, so for the moment I will do without it and then we will see if I can reinstall it.
