Despite co-operative efforts by the malware fighting businesses, there is no commonly accepted definition of what precisely constitutes spyware; some companies are more stringent than others in their interpretations, while others concentrate on particular areas more than others.
Thus the definition files of each company differ, and each application therefore looks for, and finds, different instances of spyware. For this reason, having several AS applications is good practice; while there is overlapping protection, there are also unique classes each will find.
Whereof one cannot speak, thereof one should be silent.
