I got a silicon power 16gb usb flash and it has a bad virus in it. I called "cfsdaacdfawd". I have Windows 10 with bitdefender total security 2015.

tried everything to format it, BUT NOTHING WORKS.

I have tried these:

  1. CMD and diskpart.

  2. 3rd party programs. (USB fix - Rufus - USB Format tool & ...)

enter image description here

  1. partition manager. (partition manager 12 in safemode)

  2. disabling write-protected in registry.

After plugging in the USB flash, antivirus detect the viruses and deleting them, but when I pull it out and put it in again, all my files and folders coming back again with the virus.

I even deleted the partition with "partition manager 12" in safe mode, but it automatically going to the same old format again and the files and folders are still remains.

More Information:

the virus folder name: cfsdaacdfawd

in the cfsdaacdfawd folder: aiasfacoafiasksf.vbss

Bitdefender Knows the virus with this name: Trojan.Downloader.JQVE

The flash also has the .lnk virus and make as u see. And the hidden files wont show up if i remove the flash and plug it in again.

when i'm trying to format it, right after i hit the format button, it looks like my taskbar gets refresh, i repeat my taskbar gets refresh, not desktop or my computer. please help with some more Professional suggestion.

  • Have you tried to low-level format it? There's a great and free program called HDD Low Level Format Tool. Give it a shot. Have also in mind that the reason the virus is coming back is because it would have a background process running, check you Task Manager for some weird processes. – Jesús Hagiwara Feb 27 '16 at 19:54
  • no. there is no process. when u trying to remove your memory safely from the task bar, if any process from that memory be on, then windows will say it to you. but in my case i cant eject my flash from taskbar real quick. – Saman Dinarvand Feb 28 '16 at 22:02
  • i also tried HDD Low Level Format Tool v4 and nothing happened. – Saman Dinarvand Feb 28 '16 at 22:28

The reason it comes back, more than likely, is because your PC is infected. You should find an alternate scanner like Trend Micro Housecall or MalwareBytes Home to scan your system.

  • no. as i said my "bitdefender" works like a charm. – Saman Dinarvand Feb 28 '16 at 21:53
  • this has happened to one of my flashes. – Saman Dinarvand Feb 28 '16 at 21:54
  • if windows is infected the same must happen to my other hard drive as well. – Saman Dinarvand Feb 28 '16 at 21:55

    Again, a virus doesn't just "appear" on a flash drive... There is some malacious code somewhere that's executing. If you're certain it's not on your PC then the only alternative is that it's running on your flash drive. The only executable code on your flash drive would be in its firmware - unless again you autorun something upon insertion. – Speedbird186 Feb 29 '16 at 12:12
