Help! My icons keep rearranging themselves! What is happening?

Pam instead of shutting your computer all the way down first arrange your Icons where you want them, the just let your computer go to sleep ( just leave it as is and go to bed yourself lol and when you get up in the morn see if everything is where you put it ( this is what I have had to do with my new computer and it worked for me, good luck.

You may have a malware bug, or a trojan. I had one that did the same, and I didnt know what to do and it started changing my date everytime I logged on, but then I got Avira (the free version) and it fixed it. This may not be the problem, but go ahead and do a virus scan anyway since it won't hurt.. Avira is good if you dont have protection. Malwarbytes is too.

Right click on a blank area of your desktop, choose "Arrange Icons By" and uncheck "Auto Arrange".

someone installed a rat on your pc and is controlling it when you leave.
