Whatever you are doing right now, don't ever open a .webp or an VP8 encoded .webm/.mp4 if you are on an Android phone that didn't get an update on the last 2 days or Windows 8/7.
Even if you don't open the file, you are massively fucked.

Fucking nigger moderators and the main dev are still letting people post VP8 .webm files lmao.
