Hi all, 
sorry if i post this in a wrong way but....
Windows Defender blocks the downloaded bot-file-installer ...why? Is it safe?
How can I deactivate Windows defender and be sure it's not a virus?
Thanks guys.

all our files are safe, it can detect our authentication system in the loader as a virus because it connect to russia server for example, it can also detect automation commands of bot as virus because it takes over control of pc and sends functions while you are afk.

this is called a false positive flag if your windows defender ever picks anything up it will quarantine it causing you have to allow it through the quarantine zone for it to run by turning off real time protection also
