Does my iPhone 6 have a virus?

So my phone has just randomly started doing weird suspicious things yesterday. It gets stuck on Airplane mode. For example, if it's off of airplane mode in control center, I go to settings and it's still on. Sometimes turning them both off doesn't help! Also, I was going through my storage and apps to delete things because somehow I have no space, and I found some suspicious apps. They only display the lines and there's no type of design on them. One takes up about 62 MB and the other 14 MB, when I delete them, they somehow come back. Any possible explanation? I was thinking about a reset also.

On iphone you won't get viruses. It sounds like you have something corrupted as I've never seen that on mine, so I would just erase it and start over… Easy to do.

Not possible
