The Japanese don't really do April Fools day…
/OT
Are you sure? I remember the puchi puchi keyboard pretty well and it looks like quite a few companies did so again this year. May be this is a recent development or limited to a certain demographic or interest group, I don't know. I looked at sites and feeds today that I don't often look into and disabled/reported/banned every source that's still doing a prank today. There is nothing wrong with a good joke, just getting swamped with misleading information after first April isn't fun at all. That Minimum-AV fake—if it was, I cleared the browser cache and it's still the same—get's a pass.
