Hi
Gracie - welcome to the forum!
The simple answer is NO; there are no viruses out there (at the moment) that will affect the Apple iPad; some discussion in a recent thread
HERE and plenty on the web if you want to google!
NOW, whether you want an AV program on your iPad is currently more of an issue to protect those on PCs who you may email and/or send files, i.e. although your iPad will not be infected, you could potentially pass on malware to a PC Windows computer; so depends on your own situation.
For me, I have no AV/malware installed on my iPad; in fact, when I visit sites that might be potentially 'malware happy', I use the iPad rather than my Dell Vista laptop - have had no problem! Good luck and please post back w/ further questions!
