Does my iPhone have a virus?

I didn't know where my phone was in the house, so I called it. When I found it I found a text that I didn't send to the same number I called the phone with before. Except I didn't send the texT. I think the text was sent a minute before I called but I can't be sure because it says the text was sent at 7:13 and I think I called at 7:13 or 7:14 but the call went through and the ringer went off without a problem. I wasn't using the latest OS so I just updated. Should I be concerned about having a virus?

Getting a Virus on the iPhone from a text is highly unlikely. But for safety reasons (In case it DID infect the iPhone), just restore your iPhone in iTunes. All iOS devices are manufactured to make getting viruses and stuff like that practically impossible unless the device is jailbroken.

Iphones are really secure, if concerned then just connect to itunes and restore to factory and its easily back to the way it was when you bought it.
