YOU ROCK! YOU ARE AWESOME! AND YOU ARE MY HERO!!
PS. you really have to follow the instructions very good cuz if you miss a -space- you won't get any results. If you follow the link they give you a step by step instruction
Some of the virus makes the folders inside Flash Drives, Pen Drives, Memory Cards etc to Hide.
If your memory card properties showing there is Data inside and you can't see nothing inside..,,! Then use Command Prompt Commands to see them.
Here it is how it works.
type i: (Your Drive Letter) and enter
type attrib -s -h /s /d *.* and press enter
You can now recover your Data from virus infected memory card.
