Rogue App or Virus on iphone help needed to delete

Greetings,

Recently my phone starting going haywire - I would click an app or try to text and it would appear that I pressed a different app or when I would type it would enter a bunch of other letters or numbers.  I discovered a new app on my phone that I did not download. I only get apps from iTunes and I did not jailbreak my phone. I have included a pic of the program called mfiTmitupxhw (bottom right of pic).  When I try to delete it, it says " Delete Icon ~ Are you sure you want to delete the bookmark "mfiTmitupxhw"?" I always cancel because I want the program or app deleted, not just the bookmark.  I am worried the program is running in the background.  I tried syncing with iTunes, but it was still there.  Can anyone help me with deleting this program?  The phone seems to be running okay now, no funky stuff happening, but I'm still worried what the heck this program is! Thanks!
