Why can't I download Minecraft?

I've been going at this for two weeks now. I've bought the game, I've downloaded it on another computer, but my computer at home literally refuses to let me download it. I've asked this question before, and someone said that my anti-virus was stopping it, so I needed to pause it, then download it. But I don't know where, or what the anti-virus is.

I thought it was windows firewall, but it won't let me disable the firewall, and then I try to update the windows firewall settings, and it does nothing. Absolutely nothing. I bought and downloaded it from Minecraft.net, the actual site, but when I click it, it goes to the bottom and says "Failed - Virus scan failed". I've been trying to figure out what it means, but I can't find anything.

Depressed Cousin Needs

So I was playing minecraft and my cousin who suffers from depression came and watched me play. I let him play and he was so happy:') but now he moved away and we can't play at the same time. I'm simply asking because my cousin, I know identity theft is an issue and stuff, but i'm not trying to scam or anything:/ . I do have my own account (DamianCraft) so i'm not trying to use an excuse for it. I'm not lying, and I hope nobody thinks I'm.
contact me @ damiancontreras4@gmail.com my family works in a farm in Idaho and we don't get paid very good.
i'm not saying to go buy another account but If you have an extra you don't use, please make a difference in my cousins heart, it makes him happy.

Can't create new Minecraft world?

Every time I try to create a new minecraft world, the game window freezes(visual and audio) and if you try to click on the window it will tell you that it is unresponsive. I have fully updated both java and minecraft so that is not the issue.

Does anybody know how to make this stop? I just want to create a minecraft game.

Please and Thank you to all who answer.

Added (1). I haven't played minecraft in a year, so I updated everything(including video drivers).

MacBook Air or MacBook Pro for University?

I'm having a difficult time in trying to decide between the MacBook Air and the MacBook Pro. In the fall I'm going to college and I need a laptop to go with me I'm going to be majoring in Business management, so I don't really need anything crazy graphic intensive.

I don't play computer games that much (only minecraft), but I do like to movie edit for fun (I CAN live without it though). I love my iTunes and I LOVE to watch movies (netflix or downloaded). My typical programs I'd have open are - maybe a notes/homework app to keep track of assignments, iTunes, pages/keynote/numbers document, minecraft, VLC player and maybe one other small thing or two (internet, etc.)

Would it be better to get a fully loaded 13" MacBook Air? Or the base model of the 13" retina MacBook Pro?

Any advice would be helpful!

I have found this pc that seems good for the price, before anybody says it, I'm not interested in building one! I understand all the benefits but I would rather buy one.

If you guys could give me good things and bad things about this pc and maybe recommend something better for the price that would be great! Thanks in advance!
