HELP,
After repairing XP Pro with supplied OS cd, none of my Excel files will
open. The message is "This file cannot be opened because your virus scanner
has found a problem with the file". The same thing is happening with every
single Word file in the system (Files are not available). Excel and Word file
repair facility does not make any difference nor does reinstalling Microsoft
Office 2003. Several virus scan reveal nothing and the rest of the programs
are working fine.
An suggestions. Many thanks.Ton
