Hello i am from Brazil.
Recently my clients updated version of avast and we're having problems. Our software has some emails whose body text contains encryption data, and the Avast is damaging the encryption characters. This is absurd because the avast can not change the contents of the text characters. We know that it can be turn off, but it takes a lot of work. If this keeps up we will indicate another antivírus for the customers, avast is the only one that is doing this.
I hope to be contributing, we do not need explanation, only solution. Thanks.
