Can anyone tell me how to download and link my Iphone to Wedroot?

 Hi ANYONE!
 
Having the hardest time figuring out how to secure my iphone using Webroot. I installed it on my lap-top just fine (well, within reason "Just-fine" - I Even had difficulty with that  because at first it wouldn't recognize my computer on its website) but now I can't seem to install this software on my iphone (other the "SecureWeb - which still dosn't show up as being a mobile device on webroot's website) verses "Mobile-Protect" which seems to be for buisness' only?  or is it??? I really have no idea anymore -- Because when I downloaded "Mobile-Protect" onto my iphone, it ask me for an 'Invitation-code" to get started!!!
 
WTF!! 
 
Could webroot make this anymore complicated??
 
I really have no idea what I am doing wrong, or if I am doing anything right!  - All I want is to have some virus software installed onto  my iphone, which seems impossible; having downloaded other "mobile virus software" for my iphone, only to realize that it wasn't  really virus software for mobile devices at all, but rather a means too located my phone if it got lost!
 
WHY is this complicated !!! :-/
 
Could anyone lend a hand if you could please!
