Antivirus software may also use behavior-based detection to analyze an object's behavior or potential behavior for suspicious activities and infers malicious intent based on those observations. For example, code that attempts to perform unauthorized or abnormal actions would indicate the object is malicious, or at least suspicious. Some examples of behaviors that potentially signal danger include modifying or deleting large numbers of files, monitoring keystrokes, changing settings of other programs and remotely connecting to computers.
In Chapter 4 we saw that the fact that a being is a human being, in the sense of a member of the species Homo sapiens, is not relevant to the wrongness of killing it; it is, rather, characteristics like rationality, autonomy, and self-consciousness that make a difference. Infants lack these characteristics. Killing them, therefore, cannot be equated with killing normal human beings, or any other self-conscious beings. This conclusion is not limited to infants who, because of irreversible intellectual disabilities, will never be rational, self-conscious beings. We saw in our discussion of abortion that the potential of a fetus to become a rational, self-conscious being cannot count against killing it at a stage when it lacks these characteristics - not, that is, unless we are also prepared to count the value of rational self-conscious life as a reason against contraception and celibacy. No infant - disabled or not - has as strong a claim to life as beings capable of seeing themselves as distinct entities, existing over time.
