I've downloaded the pdf for several vehicles and scanned with the free version of MalwareBytes and come up clean. Free Car Service Manuals from Operation CHARM — No strings attached!

Interesting. I managed to drill-down to oil change for our '10, and it looks to match the Repair Manual pdf I have. From the above link: Replacement — 2010 Toyota Prius L4-1.8L (2ZR-FXE) Hybrid Service Manual | Operation CHARM It only goes up to model year 2013, still, seems a good resource for gen 3 or older. If you download the whole zip file, it contains index.html: open that in a browser, and you're look at the same as the website version.
