Confirm that AV vendors are writing the viruses themselves in order to boost their sales? Good luck with that.
There are plenty of reasons why people write malware/viruses, often for financial reasons. The old days of a teenager writing some virus in assembly to infect bootsectors for the lulz is way past us. Today you're looking at malware, often exploiting social engineering, to create botnets for DDoS, spam, boosting social profiles, etc.

Occam's razor helps :)
