It has been suggested that from the perspective of signature detection, malware now far outnumbers goodware. That is, the number of signatures required to detect malicious programs exceeds the number of legitimate programs.

a. Is it plausible that there could be more malware than legitimate programs? Why or why not?

b. Assuming there is more malware than goodware, design an improved signature-based detection system.
