Virus found.000 found.000 virus or folder

From what I could determine, a legitimate Found.000 folder is NOT a virus. A Found.000 folder is created when a CHKDSK scan or other disk verification or checking program/utility is run on your computer.

However, malware often disguises itself by taking the name of a legitimate file or folder. For that reason it wouldn't hurt to run a couple more on-demand scanners to make sure your PC is clean. These products are free:

Windows Defender Offline


ESET Online Scanner



You'd also want to check the flash drive for malware. I suggest one of two ways to check. (1) With Malwarebytes installed, plug the flash drive into a USB port. Click Start > Computer > right-click the drive letter for the flash drive > scan with malwarebytes; or, (2) open Malwarebytes > full scan > select flash drive.
