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?

You can scan the iphone with bitdefender.

I became aware that in order to use Mobile Spy the phone had to be jailbroken. I was seeing if there was another software that could be used that doesn't require me to jailbreak either of our phones. and if not, who's needs to be jailbroken? Mine or theirs? P.S. We both have the ios 6 update
