I've never understood why people have to insult people who don't know how to find something. Maybe it's smart people who don't realize that not everyone is smart at the things that they're smart at. Does this have something to do with narcissism or is it it's own version of stupidity/laziness.

ELI5: Don't worry too much about jpegs having viruses. If you want to mess around with scary files on your computer, the safest thing to do is to install Virtualbox, and then install whatever operating system you want to test in there. There is no risk of exploding your computer if you do it that way.
Example; if you're running Windows 8, install Virtualbox, and then install Windows 8 inside Virtualbox to test scary stuff and generally fuck around to your heart's content. It's really not as technical as it sounds.
It's called a "sandbox". Basically, sand (bad stuff) can't get out of the sandbox unless you throw it outside of the sandbox. :)

P.S. You don't need a DSLR just yet but to have a little more freedom, getting something like this would give you more flexibility and take sharper pictures :)
