When I go to open an Excel file in Excel 2007 every so often it says in the
top left corner of my screen that it is" scanning for virus" and then says
"ready", but then nothing else happens and I am staring at a blanck blue
screen. Not sure why this only happens approximately evry forth time I open
the file. please help!

Thanks!
