XP: Minecraft PC Mods?

[tripleshot]

DS is 8 and has Minecraft downloaded on our PC. He wants a Pixelmon mod. I am clueless and tried googling but everything looks so shady and I'm afraid of downloading a virus. Do you know a legitimate site I can download the Pixelmon mod from? I really don't understand how this works and I'm usually pretty tech savvy, just not with PC games. The site I found that seemed legit had "advertisement" next to the download button, so I didn't do it.

Is this what you are talking about pixelmonmod.com/ ? That is how some free downloads make money is advertisements on the screen. Run your virus scanner to check out the program, but that looks pretty legit to me. But I could be wrong.
