<prompt> Human: So first I got multiple airline charges on my credit card that I used at Target during the whole breach. Then I got a new chase freedom card and I got fraudulent charges on that card from Target. Then I got a new card. And now today I got more fraudulent charges.What is going on and how do I protect myself?All 3 cards were chase freedom, but different numbers obviously. I do use my credit card at the self-pay at gas stations and I do go to target, what can i do?Assistant: This sounds like something beyond a Target issue. The Target breach wouldnt be affecting new cards with new numbers.Somewhere you are using these cards is either skimming them or as someone else mentioned you have a security issue on your computer if you use them online.Human: Thanks, the only thing I can think of is my computer or when I use the self-pay kiosks at gas stations. I use a Mac so I cant think of much vulnerabilities  <response>: Just because you have a mac doesnt make you untouchable. Get some free virus scan software.
