Thank you for sharing us the screenshot, Diego.
It seems that the previous version was not properly removed. We'd like to clarify that not all apps can be removed by dragging them to trash.
The correct uninstallation procedure is mentioned in this article
You can try the below steps to remove the previous version completely : 
-    Open Finder
-    In menubar select Go > Go to Folder…
-    Type /Library/Application Support/ and hit the enter key
-    Locate and delete AVGAntivirus folder
-    Reboot computer and AVG should be removed
