agree with JRock, be more careful about identity theft, it is never pretty.
But to answer the question; The easiest way to deal with it would be to plug it into a platform that is not affected by the virus (if it is a windows virus, plug it into a linux or Mac machine, or vice-versa). Otherwise, turn off auto-play, plug in the USB device, run Malwarebytes and Microsoft Security Essentials (or your personal favorite AV software on it), and then (after the virus is found and removed), start copying your files off of the drive. After all files are recovered then format the drive (none of that quick format crap, do the job right) to make sure whatever was on there is gone, and then put your files back on.
If auto-play is turned off then it disables most viruses that infect through USB drives.
Your memory card might be infected with a shortcut virus when you plugged in the memory card and does not open the actual contents on the drive or see nothing...1st thing you need to do is to scan your card first with an antivirus program then try this software
