What kind of this Virus and how to clean the USB

I got an USB that infected virus that I never seen.
I scan it in Bitdefender, Karpersky or Format it (from MS DOS).
The virus is not deleted.

That sounds like your system may be infected and infects the USB stick every time. Scan your system as described in What to do if you’re infected - eXPerience Rev.3.

Moved to the appropriate forum.

Hello ajrio2. Enable viewing of hidden files and folders. Their should be a file called “Auto.inf” Delete this from your usb and then remove the malware.

I wish I had know this forum earlier on. I had a USB that was infected by virus. I tried removing the virus but could not, so I gave up and threw away the uSB. I was lucky that I had a backup of the documents in the USB.
