doesn't recognised Safari browser and won't download!
F-Secure does not have an anti-virus product for iPhone or iPad. Even Apple says it's not needed for iOS. You can find more information in this thread:
Thanks for that, however, I was installing the software to give me some parental control, and wondered whether the mobile version would do that?
With Child Safe you can: http://www.f-secure.com/en/web/home_global/child-safe
Child Safe is a browser that you can set restrictions for. You use this instead of Safari which you need to disable.
More info: Child Safe User Guide
I would like to confirm if you are able to install the program now on your iPhone?
