I don't get this message either...
I did have this problem using a virus scanning software called "TrendMicro." It is prone to give me problems. At one point, every time I just as touched the laptop (hit a key or clicked anything or anywhere) a window would pop up telling me such and such website was extremely dangerous, blah blah blah, and it was just a big code of letters and numbers in the URL, nothing I would have been on!
After I rebooted the program my computer works fine.
I use IE, not Chrome, so I don't know how that works.
Susanne, try uninstalling and reinstalling Google Chrome and/or your virus scanning software, and see if you still get that message. It's possible something within your computer's harddrive has gotten deleted and is making your computer think the SUYs are dangerous (it's actually correct, your wallet will be harmed!
)! Good luck Susanne!
