I understand that the signature can be disabled, but most people seem to have trouble doing so when it is pointed out to them. Surely this could be made easier. However, my main question here is why Avast has apparently broken the sig delimiter in order to circumvent every email and Usenet client’s (that I know of) ability to automatically delete the sig from any reply? Any search will reveal that a lot of people are unhappy about it, there are plenty of tutorials on how to remove Avast’s signature… the fact that there are so many such tutorials speaks for itself.
