Their investigation revealed results that exonerated Fiola. On his computer it was found that a program had been remotely installed that essentially programmed the computer to access 40 child porn sites every minute. This is a computer "task" that would be impossible for a human to do by hand. Much like it would be impossible for Travis Alexander to access 70,000 child porn sites, while maintaining a full time job, a full time religion, and a full time stalker.
The Fiola investigation discovered that child porn sites had been accessed when they weren't even on the computer. One night when the Fiolas were out for dinner, their computer downloaded "thousands of porn files", at the rate of 40 per minute, to their state issued laptop. This sounds similar too. This sounds much like the evidence that shows that Travis Alexander accessed child porn 6 days after he was killed.
The CBC estimated in 2009 that at any given moment in time, a total of 20 million computers are being infected with as many as one billion viruses that are related to child porn sites.
