so I have a C and a D partition, and recently I noticed that my C partition is starting to get full, and I couldn't locate what is taking so much space. Then I noticed that my USERS folder has 90 GB and that there is a problem, and I made a mistake; since I couldn't see what is taking so much space, I marked "Show hidden files and folders" in folder options, and it seems that that has activated the virus (or malware or whatever) cause it started to do something like copying, and afterwards, I lost half of the files on my desktop. I restarted the computer, thinking (stupid) maybe it will solve that problem, and - still ignorant - did the same thing again, making other half of my files to disappear from my desktop, along with the Users folder, and emptying other folders on my C disk (downloads, pictures, music etc.). Fortunately, my pictures&music etc. are held on my D disk, so I don't have a large amount of data to recover, but still I would love to try to solve this problem without formating disk, and to try to save some documents I had on my desktop. And yes, I'm aware that the infection could have spread to my D disk and/or my USB disk & external hardrive (what to do about that? Is running an antivirus scan enough?)

I read that this kind of infection is probably a malware, but I haven't found anyone else having the same exact problem (and I googled alot). I have no idea how I scored this virus, since I really am careful while downloading ANYTHING from internet, I don't visit suspicious websites etc.

I have windows 10.

Please if anyone have had the similar experience, or suggestions to solve this problem without formating disk, I would be very grateful.
