This is kinda weird. Any help would be appreciated.
Data files, Word and Excel, on the Windows 2003 server will not open correctly. They were created in Office 2003, and when you try to open them from Work Stations, it opens the File Conversion Wizard asking which format to use.
It does this on my laptop as well, even if I copy the file to a Thumb Drive, using Office 2013. I can create new files, and they work fine. I can open local files on the workstations, without issue, but any files that were on the server prior to yesterday morning, will not open. So far the Virus Scans I’ve run on the server have been clean.
We have not done any kind of Upgrade to Microsoft Office, so that doesn't have anything to do with it.
No other Office software like Works or Word Perfect have ever been used at this site.
Files were working fine prior to yesterday. Oddly enough, the backup on an external HD, also seems to be effected.
It seems like a virus right?
