lemode-mgz redirect and minor question about Macbook Air

First off, I just want to say that I've seen other threads about this same website, but none concerning my device. So just to be safe...

Heres some background knowledge. The next paragraph down will contain my actual question.

It was around 2:00 a.m., and according to my iPhone, it was January 5th. I'm someone who's been trying to get competitive in the new game Super Smash Bros. for Wii U, right? So I was looking up information on the character Olimar from the previous installment in the Super Smash Bros. series. The website I went to was supersmashbros.wiki.com. So, I'm looking up this information on different statistics of the character Olimar, and all of a sudden I go to "lemode-mgz.com," and I'm confronted with some article with a page title of "Doctor Oz Miracle Anti-Aging Treatment." And so I shut off my phone and go to sleep. In the morning I find that my iPhone says that I have website data for "track.securevoluum.com," a website I've never been to. Now when I type "tr" in safari, it says that track.securevoluum.com is now the URL of "Doctor Oz Miracle Anti-Aging Treatment," but yet my history says that the URL is still "lemode-mgz.com." I deleted my website data after that in system settings, so track.securevoluum doesn't appear in my website data. I haven't deleted my history though.

So my question is, did my phone get some of worm virus? I haven't really used Safari since that incident, but in the times I did, that website didn't pop up again. Also, if the iPhone is all foolproof virus free, why did the redirect happen in the first place? I'm using an iPhone 5c, version 8.0.2. And no, my phone is not jailbroken. I believe it is refurbished though, so that may contribute to an answer.

And if anyone would bother to answer this question, do Mac book Airs get Adware? For I visited the website smashboards.com, and it had some really sketchy Ads...I didn't click on any of them though. But when I go to Youtube occasionally some also sketchy looking Ads appear.
