I got the "Strathclyde Police" screen-locking popup while going through the voting sites just now, can't remember which one, I was loading a bunch of them at once.

If it happens to anyone else, note that it locks out Task Manager and alt-tab, but you can still Alt-F4 to make it go away.

If you haven't heard of it, basically it's a fullscreen popup - kind of official-looking except for the usual broken English - claiming that Strathclyde police's cyber team have detected hax and pr0n at your IP address and locked your computer, and you should pay a fine to unlock it.

Erm,

On which vote website did you get that popup ?

As I said, I was doing a few at once, but the last two sites according to my history were www.top100private.com and fansitelist.com; those were the ones which would have been open when it popped up.
