I'm a little late in joining the conversation, but my card also got hacked as well.  Like many here, I only use it here and at DAZ 3D.  The credit card company alerted me to the illegal purchases and the card was shut down.  But as twisted irony would have it, one of the illegal purchases was for Kaspersky software!  The hackers got the download, but I received a copy of the software DVD delivered to my home address! 

I update my AVG anti-virus/internet security regularly, sometimes several times a day.  But it's like the hackers were looking right over my shoulder when i made my purchase here.  Makes me wonder if I have a keylogger imbedded in my system somewhere that my AVG isn't detecting.
