My girl friend took the memory card out of her camera, PUT it in a card reader, and uploaded pictures to a computer. Come to find out the computer had a viruse, can her memory card catch that viruse by just uploading the pictures.  Yes. Memory cards are like flash drives and can become infected. Below is a tool to cleanup flash drives, memory cards, cell phones etc.

Flash Drive Cleanup

Download Flash Disinfector by sUBs and save it to your Desktop.
 

• Double-click Flash_Disinfector.exe to run it.
• Your desktop and icons may disappear. This is normal.
• It will do a cleanup of removable storage devices, and write a protected Autorun.inf file to help prevent re-infection.
  
• Follow any prompts that may appear.
• The utility may ask you to insert your flash drive and/or other removable drives INCLUDING your mobile phone. Please do so and allow the utility to clean up those drives as well.
• WAIT until it has FINISHED scanning and then exit the program.
• There will be no GUI INTERFACE or log file produced.
• Reboot your computer when done.
