Last Friday (11/26) many files on my network suddenly appear with .ENCODED as the file extension. It's hit and miss around the network. It's effected PDFs, XLS and DBF file type. There's no rhyme nor reason I can figure out. I noticed one folder on Saturday and restored it from backups, but it's all over the place.
I've got Trend Micro running on all workstations and servers, so I should be protected. I can't find anything online on this. Any ideas?
If I remove the .ENCODED from the file name and open it, it's gibberish.
