Potentially unwanted programs (PUP) such as adware and rogueware, while not outright malicious, exhibit intrusive behavior that generates user complaints and makes security vendors flag them as undesirable. PUP has been little studied in the research literature despite recent indications that its prevalence may have surpassed that of malware. We have performed a systematic study of Windows PUP over a period of 4 years using a variety of datasets including malware repositories, AV telemetry from 3.9 million real Windows hosts, dynamic executions, and financial statements. This presentation summarizes what we have learned from our measurements on PUP prevalence, its distribution through pay-perinstall (PPI) services, which link advertisers that want to promote their programs with affiliate publishers willing to bundle their programs with offers for other software, and the economics of PPI services that distribute PUP.
