So i have a 16Gb USB drive, and most important is the USB have some virus in it, as far as i know they are

  • Ramnit.A
  • Ramnit.C
  • Folstart.A
  • CplLnk.A

i try so many antivirus (Norton, Kapersky, ...). They can spot the virus and delete them but when i plug it in again the virus still there

So i try to format and the window say its unable to format

What should i do now? Any idea?

Thank you!

    Looks like a virus. I recommend the following 2 things:

    Scan using Malwarebytes:

    Perform a Windows Defender Offline Scan:

    My window defender can spot the trojan, and remove it as well so i think my computer wasnt infect with virus.

    But i'll scan to make sure

    Hi Minh, do you mean you can delete those files and when you plug the drive back into your PC, the files are regenerated?

    If yo your PC is infected with a Trojan. The most popular method of spreading a Trojan is with USB flash drives, they specifically target flash drives in order to jump from PC to PC, that is why in Windows 10, Microsoft disabled Autorun on flash driver

    If the files are indeed, auto generating when the flash drive is plugged into your PC, you should perform a full scan of your PC . . .

    Try formatting through command prompt

    Type cmd in Windows Start Search box (Cortana) > Right click on Command Prompt > Run As Administrator

    Type

    format G:

    Where G: is the drive which you want to format

    Hi Minh,

    I’m here to help. Have you tried using the HP USB Storage Tool to format the flash drive? http://majorgeeks.com/files/details/hp_usb_disk...

    You could also scan the drive using Malwarebytes, here: http://malwarebytes.com

    Let me know if you make progress, good luck.
