Greetings Ashwin and Kieferschild,
Kieferschild I find your user name long and complicated to write,,,oh well
I suggest that the problem we are facing here could be caused by a USB virus. It will spread to all of your USB memory devices and hard disk.
Here is a tool to remove the virus and vaccinate your USB against further viruses.
Download UsbFix (created by El Desaparecido) on your desktop.
If your antivirus gives an alert, ignore it and temporarily deactivate the antivirus.
Plug in your usb devices (Flash drive, pen drive. External HD etc...) don't open them.
Double click sur UsbFix.exe.
Click on deletion
Let the tool work.
Let us know
