Lately a pc here had an infected usb flash drive infect it - each usb that was inserted to it would only show a shortcut inside it & its content would disappear.
While trying to clean the pc I've found a file named obupnitujr.exe under C:\Users\username\AppData\Roaming with a shortcut to it at C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.
The file is about 70 Mb & we would be very happy to get to the bottom of this & understand what it was exactly doing.
Is there a way for us to analyze the file? (notepad would show random characters)
Thanks in advance!
