Is it possible for my iPhone to have a virus?

I keep receiving this notification everytime I open safari on my iPhone 6:

"Can't Verifiy Server Identity
The identity of dsv2.rotator.hadj1.adjuggler.net can't be verified by Safari. Review the certificate details to continue."

It then gave me the option to cancel, view details, or continue. I've pressed cancel most times but this time I pressed to view the details and when I did it said "Issued by Go Daddy Secure Certificate…"

I have closed now closed out all of my tabs thinking it may stop.

Why does this keep popping up and what is it?

IPhone 6s Plus 16gb vs iPhone 6s 64gb?

I watch a lot of netflix so the 6s Plus seems appealing but I take a lot of photos and download apps and etc so I don't know if the 16gb would be enough, I currently have an 8gb iPhone 5c and that is nowhere close to being enough so I don't know if 16gb will satisfy. Best Answer gets 10pts.

I can't view any of my photos in iCloud online? Any advice?

Hi, I had my phone stolen at the weekend, reported it etc. My iCloud was definitely turned on and each time I updated my contacts it would usually appear on my online iCloud account, each time I took a photo it would also store in a separate photo album on my iPhone and back up photos was enabled in settings, anyway when I have logged onto iCloud to track y phone I also went onto my photos and they are not there, obviously I'm worried I won't get them back, was just wondering if anyone had any advice as to why they are not on iCloud, I get my new iPhone tomorrow, so I'm wondering if once I log into apple/iCloud on my new device if they will appear again, any help appreciated.
