^^^ Yes that's the cryptolocker virus, it can be in email downloads too http://www.bbc.co.uk/news/technology-25506020
That is scary!! I'm glad I don't download anything illegally tbh!!!
Um, on android I have downloaded free music, its an app.
Eta, just looked and its what was already installed on the phone and a different one on the tablet, so not illegal.
My friend says he was on a legit website - he wasn't illegally downloading, it was music he'd paid for - and he also can't think of anything he might have accidentally clicked to download the virus, which is pretty scary!
I've just changed networks and upgraded my phone, I have a free music download app called Deezer.
I do remember many years ago a lot of the kids used to use Kazaar but am guessing that is illegal as it's file sharing and no ides if it still exists.
