File Names Have Changed Colour

I'm sure somehere can help.
Loads of my file names have changed to blue for no apparent reason. I haven't installed any software recently to have done this. I have searched loads for a solution but no luck yet! :angry:
BTW the file are all different types eg-.mpg .mp3 .chm.

Thanks people. ;)

I solved the problem. :P

If this happens to you.Tools > Folder Options > View tab > Show encrypted and compressed NTFS files in color.

Voila
