This is setting off some alarms. HTTP, weird website with that just seems off to me. A few of the files I clicked on had been taken down for copyright restrictions.
I'm downloading two of them, and I'm going to put them on a system on an isolated network and run some scans. I'm not a premium member so I'm downloading them with the "slow download" option and it's taking about an hour for a 143mb download.
I'll post if I think they're safe, and while ab/dl is pretty niche market for a black hat, I'm not taking any chances.
Do us a favor and upload them to mega OP.
