Can someone hack my credit card info?

With a sniffer trojan it's quite easy to grab username/passwords and personal details such as credit card information for common known websites, dumping it to a server to sort through later on.

In the past I have come across this, tracking a trojan back to it's home, found a data dump containing over 1800 text files. Each had an IP Address plus keyboard logging, picking up on website logins. They where mostly porn site logins, then facebook, myspace, msn/hotmail, etc (a few that I tested, where working at the time of discovery before notifying and shutting it down). I didn't see Amazon on the list, but don't see why not. A few credit card details had also been picked up (didn't check those).

A quality firewall would of protected these computers from sending out those details, a virus scanner using standard definations didn't pick up on the trojan as it was buffered, it's better to have full application control. Suggestion: Kaspersky Internet Security 2012.

Most commonly no longer however psn said they were contacting the persons that obtained there data hacked they were sending emails to them so determine your email. Up to now i havent go an e mail so hopefully im trustworthy lol

Your laptop can not talk so it can not be telling you this. It would help if you told us exactly what program is telling you this.
