That looks very much like a corrupt file-system or bad drive, and not a malware issue.

try formatting the drive and then check if you can save files to it. If not, trash it.

Worried about phishing attacks?

90% of attacks start with a phish. It’s critical that IT admins and MSSPs have the right security in place to protect their end users from these phishing attacks. Check out our latest feature brief for tips and tricks to keep your employees off a hackers line!

Sorry, but if it turns out to be the infamous CryptoLocker virus, you may be out of luck.

wat is that virus???

aadihCommented:
It's a virus that encrypts all your files on your PC and demands a ransom to provide you with an encryption key to decrypt your files.

As your PC is okay and the files are encrypted only on the USB stick chances are very low that you have this virus, and as rindi suggests it could be a bad stick or a corrupted file system. Where did you get this USB stick from (or did you yourself copy files to it)?

Let's know what you find when you find the cause. Thanks.

You can see the "FOUND.000" folder. That comes from the chkdsk that ran, and it shows that you have a bad file-system. Also your comment above about "scan and fix" is what started the chkdsk.

So try formatting the drive. The data is gone anyway, and if formatting works you might be able to at least use it again (if that works it would be unlikely a hardware problem). Always make sure you use the "safely remove" option before pulling the stick out of a running system, as this is what usually causes this if it isn't done.

The data may not be gone.

You could try copying a couple of files across to the main computer and renaming them.

Then run Trid http://mark0.net/soft-trid-e.html and see if it can identify the file type so you can name them again with the proper file extension.  Then see if you can open the file and if it displays correctly.  If it does then you can consider copying the rest of the data across.

In addition to the probability that chkdsk corrupted the file system, I think you had a virus on that USB Flash Drive anyway,  There is an "autorun.inf" item that shows as a folder.  I am assuming that this is actually a file, even though it shows with a folder icon, and this has no place on a Flash Drive unless you specifically created one there, for example you copied the full contents of an installation CD to the Flash Drive.

If you did not create the autorun.inf file on the Flash Drive, then it is a classic sign that the stick was infected by a virus that uses the Windows "autorun" function for removable media as a vulnerability to spread itself to computers, then to other removable drives, and so on.  Here is an example of one type:
http://www.securelist.com/en/descriptions/old160221

If this is the case, then you need to treat all removable drives that have been connected to that computer as potentially infected, and all computers that this removable drive has been connected to as potentially infected.

If the data on the drive is particularly important, then you might be able to recover some files by installing a Data Recovery program like http://www.runtime.org/data-recovery-software.htm on a computer and telling it to try and recover data from the Flash Drive.  Generally the good data recovery programs are retail software, but they do allow you to run the recovery up to the stage where you will know whether any of the contents are recoverable.  Buying a licence at that stage then allows you to copy the recovered files out to another drive.  There are free data recovery programs like http://www.piriform.com/recuva, but usually they are just "undelete" programs.
