This is an upgrade to my post of April 09, 2017, by Earlyboomer.
I had checked my document folder and download folder and they were both "this folder is empty". I went through my PC looking everywhere I could and no files.
Then about 4 days later I booted up my PC in the morning and my Icons were back, I quickly checked my document and download folders and everything was back in them also.
I don't know what to make of this except it was like winning a minor lottery. I got a second chance to do some backing up now. I can't explain what happed but I'll take it.
I do check for Malware, because I have had attempts by malware hackers to lock up my PC but I got around that, but I was still concerned that they still might have got me.
I also checked my hard drive for errors, there were none. I upgraded from windows 7 to !0, and I am still learning the differences. I have CC Cleaner, System Mechanic, and Malwarebytes.
I do remember when I was booting up one day that I saw a notice pop up in the lower right corner of the screen, there always seems to be something there, so I didn't look quick enough, but I think it was from Malwarebytes stating it did something. You don't get a second chance to read these pop ups, they are quick, but It makes me think Malwarebytes could have eliminated the problem.
This was a good reminder, like the moderators say, we need to be prepared for anything and everything with a PC.
Thanks for the suggestions.
