Backupuser.exe is a malware or virus stored somewhere in your computer that will automatically creates (without your permission) autorun.inf and itself (backupuser.exe) in all drives such as hard disks, newly plugged USB pendrives, etc.
A side note, “backupuser.exe” would sometimes appear as “_backupuser.exe”. They would be set as hidden files and can only be seen if you have enabled the “show hidden files” option for your explorer. To enable show hidden files option, open any file or window, click tools, folder options, view tab, under advanced settings, click “Show hidden files and folders”.
It also run an infected task iexplorer.exe silently in the background.
Note: The task, iexplorer.exe, is actually referring to Internet Explorer. Thus, whenever you run your Internet Explorer, you will see iexplorer.exe in the task manager. It’s not a virus or malware originally if it’s not infected.
In this case, perhaps you haven’t notice it yet, backupuser.exe will also run iexplorer.exe even if you didn’t run any Internet Explorer. We are not sure what it does or what it is for, but it’s definitely a threat to your computer.

Note: DO NOT FIX CHECKED EVERYTHING OR ANYTHING THAT YOU ARE UNSURE WHAT THEY ARE, IT MAY BE YOUR COMPUTER VERY CORE SYSTEM’S TASKS. I would like to make it clear that I am not responsible for any loss or damage you may incur by results of using this application.
After “fix checked” backupuser.exe, restart your computer and it will be GONE forever unless there is any USB flash drive or Pendrive that were infected before being plugged into your computer.
Another solution for this problem is to scan your computer and any drive you have with high ranked antivirus software such as Kaspersky Antivirus or Bitdefender Antivirus. We have tried scanning with the Free Avast Antivirus, but backupuser.exe somehow cannot be detected. Perhaps there are other antivirus softwares which might possibly detect it and clean it right away.
