How to remove shortcut virus from pendrive

The most commom virus menace for Windows users is the shortcut virus changing all your files and folders in pendrive to shortcuts. It's a familiar problem among most college students. We have all tried to use the ineffective shortcut virus remover, a third party software, to solve the problem. But it is very simple to deal with.

1. Delete all the shortcuts from the pendrive. They can be identified by the arrow symbol in icons and having a size of less than 4kB usually.
2. Now open command prompt.
3. Go to the pendrive by typing <alphabet assigned to drive>:
4. Now enter the magic line attrib -s -h /S /D
5. Wait for some time... It's done! All your files and folders are back.

The secret behind this:
The virus only changes the folders' system attributes, makes it hidden and creates shortcuts. So by removing the shortcuts, and removing the hidden and system attributes from all files and folders, you have terminated the virus without trace!
