Recently, I typed something for the forums, saved it on my Flash, then went down to the café and plugged it in to use it, and when I went to open the txt. file, I found that what I had typed was gone, and there was this message saying that if I wanted my stuff back, to send an email or something like that to some address. Of course, I had the wisdom not to do it.
But then I downloaded some voice acting material, and in place of what I had expected, I found some audio reading of the same message I had found there on the txt messages I had lost.
On top of that, it also put this Microsoft Excel-like file(with that as its filename) on my Flash disk. And from experience I have learned that when there are weird files on your computer, and you have no idea how they got there, it's best to assume that it's a virus.
And there must not be any updates for it, because at all the places I had scanned, it said that the flash was clean.
I wish I could find that moron who made it and rip his arms off, he deserves it.
