<prompt> Human: This has happened to me multiple times and I have gone through 3 credit cards due to this. Every time I travel to a different state I get a fraudulent charge on a credit card from my credit union. And every time I get a new card.I dont store my credit card information in any database or online retailer. Also I only use https retailers and pretty much stick to the tried and true merchants online Amazon, etc. Recently, I had to remove a 1000 charge for concert tickets in Georgia after a visit to Georgia for the holidays. This card has been in use for about 3 months so Im confused on how this happens. I didnt even make any legitimate purchases in Georgia with credit. It seems I might have a key listener or something on my computer. Some how the thieves know my travel plans ahead of time and make purchases in the states Im visiting. This has happened more than once visit Indiana, get fraudulent Indiana charges etc. What can I do to protect myselfThis is getting annoying and is kind of scary because it keeps on happening to this particular credit account. My credit union is understanding and will return the credit to my account but I want this to end!  <response>: uwisemagick1 has it right. change accounts. CLOSE the accounts you have... get cash in hand... walk over to the happy helper sitting at the little desk, and act like your new. brand new EVERYTHING. Show them this is in their best interest or theyll keep eating 1000 fraudulent charges.I like the reinstall OS option too. Cant be to safe. Change your passwords. Sounds like your ripe for a real problem of identity theft if you dont put this problem to rest soon.
