Hi, This morning I got a pop-up from ESET (see attached pictured) telling me that a potentially unsafe application had been found, called cpuz139_x64.sys. I assumed that it was from CPU-Z, which I formerly used, so I uninstalled CPU-Z but the problem was still there. I had ESET clean the file and restart, and the file was successfully deleted before the restart, but after the restart it had been re-created. I then tried restarting in Safe Mode and manually deleting the file and was able to do so, but on restarting to Normal Mode it had been recreated, so I went back into Safe Mode and deleted it again, then restarted to Safe Mode and it had not been recreated, then when I restarted to Normal Mode after that, it had been re-created. My question therefore is: 1) Is this a false-positive? 2) If it isn't a false positive, how do I trace it back to whatever is recreating it each time and solve the problem? Thanks.
