In my junk folder in hotmail some emails have started to come throu with a blue arrow next to them, its pointing down, what does it mean?

It isn't all of them, and I haven't opened or replied or forwarded them.
Unless I just don't see it, is there a "select all" option, for when I want to delete messages?  It's easy in Hotmail, but not so in Windows Live.
How do I edit an address, the only change being one letter from lower case to upper case?
the title explains everything, your forum section sucks, how about creating a section for specific problems, and fix what the **** is wrong

THIS WEB PROGRAM ON YOUR COMPUTER.   That statment is in yellow, then in the main content of the message it says: the program will open outside of protective mode.  Internet Explorer's PROTECTED MODE helps to protect your computer.  If you do not trust this program, do not open the program.

NAME:  Silverlight.Configuration.exe

PUBLISHER:  Microsoft Corporation

 

then it asks if I want to allow or not allow - except my screen is COMPLETELY frozen.  I can't delete, check the allow or do not allow, nothing.  I have to shut my computer down to get out of the hotmail system.  Do I have some kind of virus?  What can I do to get this fixed?  Any help will be greatly appreciated.
