I have had my iPad for two days but clicked on a site today in Safari and a bunch of malware flew in! I read I am to restore the iPad if this happens but now can I prevent this in future? What I did actually is restore from back up to avoid having to reinstall all my apps, as my apps are greyed out when I sync the iPad with computer. How common is it to get malware on the iPad? And is restoring from back up sufficient to remove malware, please?
