I recently downloaded a file (A highly compressed file containing GTA SA, which thankfully works). It came in an executable file, but, I was too stupid to read the instructions, and instead of entering it via Winrar, I double clicked on it. A MS-DOS window opened for a couple of seconds, then dissappeared. Now, not only can't I find the process within the task administrator, but I can't delete the file, and even when I restarted my PC, I couldn't delete it.
Is there any software I can use to find the process, or anyway I can actually delete the file :P
