Do I have an iPhone 5 virus?

I've never heard of an iOS virus, but some really weird stuff has been going on. First off, the iPhone will randomly exit out of apps and stuff for no reason. Sometimes I'm able to open it again sometimes I can't. Eventually I'm able to, but not necessarily right away. Then my music is acting really weird. When i try and play a song, it goes to the song then just spasms, flipping through all the songs, attempting to play them all. Then it exits to the song menu of the music app, showing that all the songs are playing at once. (Has the little stop symbol next to them all indicating that they are playing) This is really weird. Any ideas?

It would be really rare to get a virus on iphone unless you jailbroke it. You may to just restore back to factory to see if that fixes it.
