People + AV's = A lot of different opinions and theories and bs. But a lot of people have valid points, and i'm always all ears.
I will definitely end up using those links that marsmimar provided. I've only used VirusTotal.com and they limit size and file types, and their definitions are usually out of date i think...
I've heard good things about MSE, and will check in to that as well (Why not?).
As of right now i'm using MalwareBytes (Paid), Eset NOD32, and Comodo Firewall. Within my virtual machine i'm using Avast. Once i get a chance to scan this "iffy" external with all of them i'll try and post something juicy.
Thanks for all the replies. Keep 'em coming. Ya'll are the it. LoL
