Risk Issue on my USB Drive

Hi,

I have a problem with my USB Drive. After the USB has scanned by SEP, apparently detected the virus is W32.Slugin!. But the scan process can not completely because the USB is unplug by itself. I've try to using Hiren's CD Boot to recovery and backup files on USB Drive, but is never succeed cause the USB always unplug from the PC machine by itself.

Is there someone who can help me? Can you tell me the best solution, or give me a software tool to solve this issue?

Thanks & Regards,

Barkah
