So, my computer started running abnormaly slow and suddenly this window appeared out of nowhere, telling me that I have to pay a ransom and that my files are "encrypted". I looked at my music folder and I noticed that all my flacs and mp3s now end with the extension ".wanacry". Then I checked my work documents, my Sup Forums folder and my movie folder. They're all unusable.
I don't even know how this happened. I don't torrent anything and I get (literally) everything legally. I also have latest version of Windows and I even have an adblocker. I didn't open any suspicious emails either.
I'm scared, Sup Forums. What the fuck do?
