USB drive, unable to view hidden files after virus

by gnw1976 / December 2, 2008 1:20 PM PST

Hi, new to Cnet. Have searched a few forums and found similar issues but have followed the advice and unable to resolve my problem so calling out for help.

I am travelling in S.E. Asia and have been using a Cruzer USB stick as a storage device for my photos (regularly transferring from my digital camera to USB). Also have some documents on the USB relating to flight bookings, accomodation etc.

Along the way picked up a virus. Unsure which but used a hotel AV software to remove it.
The virus symptoms: set my files and folders to hidden and created files with same name but .exe extension in their place. I normally have hidden files visible so i saw through the charade immediately and did the cleanup. After the cleanup I have a few of the folders and files hidden and am unable to set the values to "show hidden files". I followed instruction from another Cnet forum and used the flash disinfector tool; and also UItool (repair option).

Current Problem: I am now able change the folder options to show hidden files but.... they are not shown. I have used MSDos prompt to display the hidden files/folders and confirm they exist. I aslo ran an AV scan again this morning (clean result using hotel PC (VirusScan Enterprise) which showed the files being searched and listed the hidden files.
I am also able to use properties tab to show the folder sizes and comparing that to sizes of visible folders confirms the other files/folders still exist. I just cannot see them.

Very concerned as not only do i have info and a lot of travel pics "hidden"but my camera was itself infected and so the DCIM folder is hidden and thus i cannot copy/move pics off my camera.

Any suggestions would be truly appreciated.
Thanks

You could give the following a try......
by Marianna Schmudlach / December 2, 2008 1:42 PM PST

Flash Drive Disinfector
Download Flash_Disinfector.exe by sUBs from Here and save it to your desktop.

o Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.

o The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.

o Wait until it has finished scanning and then exit the program.

o Reboot your computer when done.

Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder...it will help protect your drives from future infection.

IF the above doesn't help......

Go to Start --> Run, then type Regedit

2. Navigate to the registry folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL


3. Find a key called CheckedValue.

4. Double Click CheckedValue key and modify it to 1. This is to show all the hidden files.)

Ive solved the problem
by gnw1976 / December 2, 2008 11:12 PM PST

Thanks, I tried both of these earlier today with limited success. The change to the registry did allow me to be able to set the "show hidden files" flag (but doing so doesn't reveal the hidden files) and the flash disinfector doesnt seem to have helped.

I have been playing around in msdos and solved the problem.
I learned the files themselves were not hidden. I was able to copy files using xcopy and they were all visible in the destination location. The problem was that a number of folders were hidden. I tried to use the command "attrib -h" to change the attributes of these folders but cannot as I get a message saying "Not resetting system file" so i used "attrib -s" to remove the system file attrib and hidden attrib and now all is good.

Thanks for your help and the quick response.

Having the Same Problem

In reply to: Ive solved the problem

Just not exactly sure as to how you were able to come to resolve it.
Problem has also prevented me from seeing my pictures on my camera also.
Any assistance in the matter would be greatly appreciated.

Sincerely,

Darrell..

It would be in your best interest, to start a thread of your own. New posts (in a two year old thread) tend to get lost. If you do choose to create a thread of your own, make sure to include exactly what your problem is. Paying special attention to what you see in red above the box where you post:

'Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.'
