Hi all, This file "FAF60000" suddenly appeared on my desktop. It's shown as .xlsx file. I didn't download. Tried to get info, but no window pops up to show me the info. Tried move to trash or delete, but "file cannot be deleted". Tried to go finder to look for this file, but it's not shown. Tried deleting on Terminal, but no such file. Someone help pls? Tks!
