hi,have a question,

i know it would usually creat a lot of alerts if i try to install a new software on my pc with defence+ were setting on clean pc mode.so i set up a new folder,and added this folder(with “include files from subfolders too” ticked) to trusted files.then i downloaded the latest version of adobe flashplayer installer(for ie) into this folder,and ran the installer.however,it still created defence+ alerts during the process of installing.so what’s woung with it?i can not understand why running a trusted file would still creat defence+ alerts?

Trusted applications cannot launch other applications without a request pop up, System applications can. The installer exe likely calls another exe and that’s why your getting pop ups.

I get usually 2 questions per installation.
Explorer exe tries to run something. OK.
This file wants to… OK, treat as installer or updater.
(Both answers were not marked with “remember my answer”.)
Done.

In contrast to your wondering, its perfectly fine that new files in a trusted folder are not trusted. You did not give your consent.
