Weird stuff is happening...

[Haswellx86]

From a very long time I have been noticing some wrong and weird stuff Windows is doing, but I though and still maybe think that those are just malfunctions, but maybe a chance of a malware? Symptoms:-

 

1) Whenever I use Google Chrome (I use Edge, proud of me yet Microsoft?), and when I close it, sometimes a blank folder with the default name (new folder) is created on the desktop at the same place, and I always go delete it. Suspicion - [malfunction - medium, malware - under medium]

 

2) A long time ago, this problem occurred that a framework or whatever inside Windows broke or something, leading to Microsoft Store, Search (fixed), and many MS account or other internal stuff not working. I already had this problem occur on my old device, and re-installing Windows fixed it. [malfunction - absolutely, malware - nah]

 

3) One day I was just moving a large folder, and it suddenly just disappeared and no where to be found, tried running even data recovery. [malfunction - most probably, malware - could be]

 

4) A folder with copy of GTA SA, now does not seem to be found, when I quite don't remember deleting it. [malfunction - could be, malware - could be]

 

5) I just went to this location in file explorer - C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\sound\mvp. So its just a location inside my CSGO game library inside Steam files, but what I found in the "mvp" folder there were a few music files, which absolutely should not be there inside the game, like GTA SA theme, illuminati theme, John Cena etc., but it also could be at some point they were played my another player in the game and for some reason the game saved it or something , I don't know. [malfunction - hmm, malware - could be]

 

Now that I think about it, it doesn't really seam that my PC might be affected, because a malware should show some obvious symptoms, and should be more harmful, but it isn't, and I don't even see any activity in the background in task manager. But I don't know, I just want to get rid of the mentioned problems.
