Hello megalodon99,
A better way to handle a security suite that's blocking software you trust enough to run would be to add an exception into Avast Security, so that it doesn't block the previously mentioned software. To add the exception open Avast Security Dashboard, click on the settings cog in the top right, then click on preferences. Along the top of the new window you will see different icons, click the one that says core shields. Under file shield you would add the application in question. However before adding any file to this exception list, you must know that it isn't a malicious file as the Avast Security suite will not block this file after it has been added.
