This was just now, on the work PC that never ventures anywhere unsafe and is regularly cleaned/updated. Secunia score 100%, ASC active, AVG up to date etc etc.
I'd guess if others were seeing that many there'd be a few more vocal protests.
That's the one and only time it's happened, just don't know if the glitch is my end or the server, thought it might have something to do with each person attending have hotlinks etc.
