HT4993 anti-virus/anti-spyware for iphone

Question

Is there anti-virus or spyware software you can download on your iphone or ipad like you can your mac?

Answer 1

I was told using free public wifi allows others to have access to the devices using the wifi... Is this not true?
Not quite true, no. It's not true that using public wifi gives people access to the device. What it does is allow people on that network to snoop on any unencrypted network traffic. So, if your phone is transmitting a clear-text password for the account that got hacked, that could be captured by someone else on the wifi network who has the right software on their computer.
That said, though, the chances of that happening in most places is not high. Perhaps if you were on a very large open network, like in an airport, or if you were in a country that doesn't have particularly stringent laws against hacking (like Russia), then it might be more likely, but otherwise it's far more likely that someone simply hacked your account remotely. Probably the password was not as secure as it should have been and it got cracked by brute force.
