I downloaded a jailbreaking software and didn't realise but it came with lots of viruses. I jailbreaked my iPad and when it was done, Cydia wasn't working, neither was Safari. So I went back onto my computer and a warning came up saying that my computer was infected with trojans and so on. I plugged my iPad in and tried to Restore it on iTunes but because it was infected, iTunes won't start up. How do I get iTunes to work so I can Restore my iPad to get Safari to work again?
