Supernatural episodes!

Okay so ive seen alot of the new supernatural and love it and i really wana watch it from the beggining but i dont have netflix or anything so i was wondering if anyone knows a site THAT YOU HAVE ACTUALLY USED and trust not to have a virus that i can watch it on or.....maybe if you already have it on your laptop or something you would be willing to upload it to youtube in parts under a different name so i can find it???

btw has to be free to watch!
