μ Virus on MMC with paramount data

Hello,
I wonder how to fix this issue
Memory card was working fine on my Samsung SII until I connected to an open wi-fi network,

Folders' names changed to have Meu μ at the beginning of its names .
i see this only when i browse MMC contents on the mobile but when I connect the MMC to my computer and explore it I don't see the meu μ sign

,Paramount photos,videos and documents which I didn't have the chance to move to my PC are on this tiny (thing) *

Kindly inform me how to recover every thing from the MMC before doing any format,
I cannot take the risk,please tell me what to do,
MMC is 4 GB yet some files show properties to be 27 GB !
Doesn't allow me to copy when connected to PC through a MMC reader,

other MMC cards work fine,Please help*
Thank you,

Tried ALL the useless data recovery software with no benefit at all. Didn't format and will not format the card, hope to find the professional exceptional help here :)
