IPad – How to detect malware and remove it from iPad

I have not heard of any exploit that would produce this behaviour.

The fact that the pages DO load, and only switch to another page AFTER they have loaded, indicates to me that the problem lies within the page itself. For instance some "evil" Javascript is inserted into the page causing it to redirect.

If the problem was in the OS, for instance messing with DNS, I would expect that you would never be able to reach the page and you would immediately be getting the "evil" page.

Ad networks have often been used for this kind of abuse because there are many parties providing content for ads, so it is hard to check everything that goes on. I would think that an evil advertisement is much more likely to be the cause of this problem than any malware on your iOS device.

You could try using your iPad via proxy and monitor the traffic that comes through. You could set your computer to share its internet connection over Wifi, and run a html proxy on your computer. And then look in the transferred code to see if you can identify the cause of the redirects.

The date was lost when you let the battery run flat. Once you reset it, it should be fine.

Check out Adware Medic (donationware) for any other PUPs, then run Avast again to see if it finds anything else.
