This file installs a driver for a USB card reader. I can't get it to run with Malwarebytes on. To reproduce Run the installer, click Next, Next, Install. The following message pops up and the installer quits with a warning. My analysis The file Service.dll is created by the installer. It exists for a short time period before being deleted (even MBAM is unable to quarantine it). I believe its role is to do some pre-install checks. Seems the file is not part of the installer's internal file archive because I was unable to retrieve it with MSI unpackers. The file's lifetime is visible on Sysinternals Resource Monitor. I couldn't isolate the file by myself. Other remarks The MSI file is reported clean on VirusTotal but if you go to the Additional Information tab it says "Last Saved By: DavidHacker" which doesn't exactly inspire confidence. Hope you guys are able to isolate Service.dll and confirm it is a FP. Thanks
