This may only apply to UK players, but there are currently some bogus videos when you click on the grey bar in the Watch Videos section. They came on late last night. There are 7 of them currently; 3 occurrences of one video, 2 occurrences of another, and 2 occurrences of a third, all supposedly videos advertising Sony.
Don't know if they have any viruses behind them or not, but I would suggest not clicking on them. If you do click on them they simply don't play but take a long time loading. I clicked on the first one and after a while it timed out saying the server took too long to respond, but the web address it went to was videos.prankies.com... which does not sound like a legitimate site.
