I ran across this file on my SSD and Im not sure where it came from, it has no location and when I open it in notepad it says "OK" .. its 1KB in size. Would this be from a trojan/virus of some sort? I ran Malwarebytes and it removed the files from my computer but this on is still here. Any suggestions on what it is and how to remove it? My PC still runs smooth and fine I just have no clue about this file, thanks.
