It's only recently been reported by Sky, that a numerous amount of their Android apps have been hacked and replaced on the Google Play Store. As you can see from the screenshot to the side, it's a group calling themselves the Syrian Electronic Army. At the time of writing this up the affected apps are Sky Go, Sky+, Sky WiFi and the Sky News app.
Sky's official support account (@SkyHelpTeam) has advised people who have these applications installed on their Android devices to uninstall them and they will be notified (via Twitter) when it's safe to redownload them again.

If you're not that tech savvy and are unsure how to uninstall any of the Sky applications from your Android phone then follow the steps below.
1) Open your main menu and scroll down to "Settings".
2) Scroll down and select "Applications".
3) Select "Manage Applications" from the options.
4) Locate the Sky application(s) and click it.
5) Click the Uninstall button and wait for it to say that it's uninstalled successfully. That's it. Done.
All that's needed now is to wait for confirmation from Sky that the applications are all restored correctly in the Google Play Store, then you will be able to reinstall them all.
