Kid is an Adult.zip

Just got a pri­vate mes­sage on Last.fm from intu­itionor­phan, sub­ject “I hope this makes sense to you,” body “I have an earnest desire to change the world,” with a Medi­aFire link to a file named “Kid is an Adult.zip.” I’m cer­tain the file con­tains some­thing bad, but I’m curi­ous about which or what kind of bad thing it is. None of those phras­es turns up any rel­e­vant results on Google.
