Lost Files!!!!

Microsoft Windows XP

Can or does anyone know why I can not locate and files on
my comp. I had the "Blaster Virus" and thought that it
was patched up when I got tech. support from Microsoft ..

I seem to get the same message everytime I try to log on
to any files that i have downloaded.. If anyone has any
suggestions, please feel free to reply!

Thanks for your spport!
