Kaspersky Anti-virus version: 21.3.10.391 (j), Windows 10 version: Home 19045.2251

Text translated into English, so it may be a little different from what appears in the English version of Kasperky Anti-Virus

As shown in the picture below, the anti-virus is detecting a file (Oinstall.exe) as malicious. I already put the file as "trusted application" and as "exclusion" but the anti-virus continues to detect and generate the photo message.

What can I do to make him stop asking me?

 

Hello @Alan Cardoso,

it would be better to use a legal office version.
Besides MS-Office there are Open-/Libreoffice and other free versions.
We do not support piracy.

 I actually acquired my MS Office from Microsoft's website, so I'm going to try to understand better why my PC is running a non legal version. I will try to understand better. Nevertheless, any for Kaspersky to stop showing the message?

That OInstall.exe it's a known hacktool tool which comes with integrated activation tools.
