Icon won`t open?

[Sherriff]

Hello,
My icon are all blank paperwith a fold on the upper-left corner , when I click on the icons (any type , even something like MS Word ) it asks "Choose the program you want to open this with" and gives you a few options. How do I correct this ? Is it maybe the virus on the software suppose to open it or what ?
Thank you.
Collin

Would help if you posted what happened before this started and what operating system you use. What happens when you select the right program for that file? Does is stick?
