Hi! I recently downloaded a beta version of a modified program called "Avogadro-Orca4.2.1" which is still in BETA version: I downloaded from the official ORCA website orcaforum.kofo.mpg.de. I need this program for my work. However, as soon as I install it, Kaspersky deletes all files and even when I restored them and added everything to exclusions. The program couldnt work. Is there a way to install Avogadro safely? Thanks in advance for your help
