Some Virus has corrupted many of our Microsoft Office files and PDF files.
We have an issue where many of our Microsoft Office files (excel, word) and pdf files have been corrupted. I get errors saying that the 'File is not in a recognizable format' for excel. The PDF files says that it's not a supported file.
Even pictures files are corrupt. Excel and Work will open the file but it is all garbage characters everywhere.
We are on an older version of SEP (11.0.6300.803) and I'm working on getting the update. Is this a known virus? Can we recover these corrupted files?
Our backup retention period pass so I could not recover from backup.
