Photoshop CC Deleting the files

I am Currently facing an Issue that has ruined a lot of my work and has been remained unsolved since months. At the very first time when I faced this issue, I just completed a project which took several days to be done. I had many more JPEG, PNG, Mp4, Word, Text, RAR and ZIP files on my desktop; They were all part of a project I was working on. After Finishing up and saving evrything I closed all my programs (Chrome tabs, Photoshop, MS Word, Notepad) and was just about to shut down, when all of a sudden I was shocked and fumed to see a completely empty desktop screen with Only ONE damn remaining item THE BLOODY RECYCLE BIN.

This is the problem >>>  Photoshop CC Deleted the files on Desktop.

I thought it was due to the cause of some malware. I Bought the AVAST premium membership and felt secured that now my work is secured to it's maximum absolute (as it was the first time I was Using a paid AntiVirus).

I again worked a whole week on another project and experienced the exact same problem, the only difference was that this time I only Closed One Program Adobe Photoshop.

At that time I assumed that Photoshop might be the cause of this and so only to test I copied a few files on my desktop and opened up Photoshop and Closed it again, BINGO, my assumption was a fact now and so from that day on all what I do, I save it in My D Drive partition. Nothing Happens to the D drive but whatever I save on my LOCAL DISK (DESKTOP) gets deleted after closing photoshop.

There is no virus, No malware, Not Drive errors. The Most Absurd part is that the files are literally being wiped of from existence. There is no history, No RAW files, Nothing. I have checked multiple times with many various ways but I am unable to Solve This.

I am Using Latest Photoshop CC.

Kindly provide some guidance ANYONE ???
