I assume that this is not an uncommon problem, and that TP protects it's system from this type of virus? Recently I got the virus on my Memory Stick PRO Duo while using public computers in Asia, and did not discover the virus until my card reader was connected to my home computer, which has Avast. In the interim, I uploaded quite a few images to TP, and was wondering if I could have passed the nasty along to others?
Simply put (not 100% accurate, but accurate enough to answer your question here) :
Images don't contain executable code, and you uploading photos won't have transferred the virus. The virus would be a program hidden in the boot sector of the memory stick; that program is a completely separate file, distinct from the photos. Only computers which you physically plugged your memory stick into would've been at risk.
It was good of you to tell us, I for one appreciate it,
I'm not sure about the PRO Duo series, but some Memory Stick models have a write-protect switch that allows you to lock it, and thus preventing any files to be written on the card. This is useful when you need to plug it to public computers.
I just checked the Sony book about the memory stick - it says some sticks have a switch and some do not. My stick does not have a switch - however, my camera has a software lock for the stick. Thanks for the info - in any case, I'm about to get a new Olympus camera since this 2 year old Sony is not producing the quality I want. I'll be sure to research the features of the Olympus and it's memory card a little better this time!
The best way of tackling this problem is to disable the Windows Autorun feature so that the operating system won't read the USB stick when you insert it. Illustrated instructions can be found on this site: How to disable Autorun
