Pdf file is see through/blank and displays a weird date for the title
I had a weird glitch in adobe reader XI and wanted to see if anyone had ideas as to what caused it. I had several pdf files open and I am not sure if I had closed them all or not but after being away from my computer at least 20 minutes I had an open pdf file that was named July 16, 2018 (this happened on the 18th and I do not have any files with that name), it said page 1 of 7 but was blank where you could see the screen through it and wouldn't let me do anything. After closing the file no other pdfs were open and this file did not show up in my recently opened files. Everything opened fine after that and I have never had this happen before so it has me a little worried that it could be a sign of a virus (unlikely but never can be to sure). I am thinking an open file got corrupted but can't recreate the event and am not positive that a pdf doc was actually still open but I don't know if adobe could just open on its own like that and create a random file. Has anyone ever experienced anything like this (any help is appreciated)?
