How to transfer videos from my laptop to my iPhone 6?

So basically, I made a video on my canon eos t6i and I have been struggling trying to figure out how to transfer the video from my Asus flexbook laptop to my iPhone 6. I edited the video on Windows movie maker and I believe that I saved it in the right format for iPhone (MPEG). I've tried looking for answers on the Internet, but none of them make sense. I have tried transferring it through iTunes but I'm hopelessly confused. I'm all new to this laptop and this camera, so if anyone could give me tips as to how I can transfer this video, please let me know.

OnePlus One, Iphone 5, or Iphone 5c?

I've always had android. I need to upgrade my phone because my last one (moto g) was stolen. Should I get a used onestep one for $170 in good condition, a mint condition Iphone 5 for $165, or a 5c in good condition for $155? I have always been curious about owning an Iphone, because I have always owned android. Is this 5/5c obsolete? Would they be still running well in two years?

Wi-Fi won't work on iPhone 6?

My dad blocked the Wi-Fi and pretty much everything on my phone and recently he unblocked everything but my home Wi-Fi still doesn't work. It works everywhere except at the home one, so what's the problem? It connects but doesn't load anything, also please note that it works on every other network (starbucks, panera, etc) except for ours.

How to check if I have a virus on my iPhone?

I would like to know if there's a way of checking if my iPhone has a virus. I use a site called Putlocker to watch movies and tv shows. That site has lots of pop ups. Few pop ups go something like "Congratulations you have been hand picked by Facebook to win a prize" then I have to click OK (no cancel button)

Anyways my Mom said she watched on the news a while back about something similar like that, only it was a text message and the individuals information were stolen when they clicked on the link.

Now I don't fall for those kind of stuff, but I'm still worried that my phone could have a virus. I have a iPhone 5s IOS version 8.3. Can my service provider (Boost Mobile) do something or will I just be wasting money and time?
