Could there be spyware on my iPhone ios6 beta 3?

I updated from a download file from a popular youtube video a while ago. My friend told me they could of encrypted the file(?) or something like that so they can access my stuff because i upgraded from there file (and someone could of hacked that upgrade file).So is it possible to spyware on my iPhone? [My iPhone is not jailbroken in anyway]

No apple has a secure protection in all apple computers and iphones, ipods, and ipads so you don't need to worry

Yes it is possible, scan it with anti virus.

  • Virus or Spyware on iphone 3GS? I was checking my email earlier on my iphone 3GS and opened what I thought was a legitimate email from my friend but it turned out to be a spam mail. I clicked on a link and it brought be to a website about working from home and so on. I'm not sure if it had any virus or spyware attached to the link but is there any way I scan my iphone for this? Or do iphones by default not get any virus or spyware?
