Malware and spyware wasn't generally sophisticated enough to do this type of data collection and targeting. This is a ton of work, as evidenced by the 10s (maybe 100s?) of thousands of engineers employed doing it today. The data Malware and spyware went after was your credit card number, and bank account & passwords. Which they then used to steal money from you. No one ever was worried that malware would build a profile of them and sell it to internet advertisers who would send them more relevant ads.
