Recently my computer contracted a rather large virus that caused about a day
and a half of downtime. Everything seemed ok and normal once I debugged the
computer but I recently noticed that about 12 spreadsheets in my computer
have been lost. These are all the same title, just different dated versions.
I still see them as saved in the files, but when I try to open them I get
the following message-

"FILE NAME" cannot be found. Check the spelling of the name of the file, and
verify that the file location is correct.

Nothing has changed and it wasn't saved elsewhere. How can I gain access to
these files?
