Linux u disk virus can not remove the solution

When using a USB disk under Linux, every time you see a file like auto, it is suspected to be a virus.

But the input ls-l command found that the attribute is not completely?

The result is that it won't be erased.

After a multi-party query that the reason is that Linux can not deal with the "." End of the file. So in this place cannot be deleted.

But there is a solution.

The method is as follows:

If you are the system automatically mount a U disk, please umount first

Then, enter the following:

sudo mount-t msdos/dev/sd*/media/disk

The difference here and the default is

The-t parameter changes from VFAT to MSDOS. Because VFAT is for FAT32. MSDOS is for FAT16.

When you open the U disk again, you will find. The name has become Autorn. Because the FAT16 file name can only display 6 digits. If there is more to use, omit.

But this will remove the virus.
