How to Enable Files Hidden by Virus on Pen Drive

My pen drive was infected and after I cleaned it with my antivirus, it showed some virus and Trojans moved to virus vault. However, thereafter the contents of the pen drive have become hidden and they won’t get 'unhidden' even after I asked the computer to show all hidden files. I "googled" for a while, but couldn’t find anything so I called my hommie Harry aka "m3katron1x" who was kind enough to show me this quick and easy way of enabling these hidden files.

1. Connect the affected pen drive

2. Launch command prompt by typing "cmd" in the run window (windows button + r)

3. Log into your pen drive i.e. "J:", where "J" is the drive letter of your pen drive

4. Type the following command i.e. "attrib -h -s *.* /D /S"

5. Go to "my computer" and open your pen drive. All your old (hidden) files and new
ones should show up now.

Here is another process I found by "googling" one day after work:
1. Open up command prompt as before

2. Now to remove virus's attributes (in order to delete it type following line by
line and execute them pressing enter.

3. F:\

4. F:\attrib -s -r -h *.* If there are any malicious EXE files those are now visible
so if unnecessary delete them too.

5. F:\del autorun.inf

6. After finishing above, quickly remove the pen as soon as possible (just after
executing del command).

7. Now your pen is without virus activation config. file. Now you can safely delete
unnecessary EXE files on it.

Let me know if it works...
