<prompt> Human: I dont know what to do at this point. I am super careful with my credit card usage: only use at reputable retailers, only used on my computer for online purchases with firewallanti-malware...What can i do to keep this from happening? At this point Im ready to cancel the card and get something else.Help PF!Assistant: You might have a key logger on your computer. Malware and firewalls are not 100.Human: Ive formatted a bunch of times, and use those aforementioned things to keep protected, not sure what else I can do from an online purchase perspective. Assistant: Have you done a credit check recently? If you have an account compromised repeatedly whoever has managed to get access to that information may have gained access to more. If so, they might also be opening up lines of credit in your name etc. Also, things such as changing your e-mail password, checking the mailing addresses listed on your accounts online and changing those passwords also helps as some basic steps. Years ago I had a problem with one of my bank account debitcredit cards getting its number stolen etc repeatedly. The only correlation was that these charges occurred around 3 weeks to a month after I paid a visit to the local dental office. So there was some problem in their system... that same complex also had a physicians office the staff of which were repeatedly caught dumping confidential client files in to the non-secured trash bins outside. Once i stopped going there.. the problem ceased.That leads to my final question, are there any businesses, services etc. that you have used that seem to correlate in time to your card number unwanted charges etc?Human: I should do a credit check, a very good idea.I really honestly dont shop or use my cards much. I really cant find a pattern. Today when my account was hacked, there were three charges in 3 different states. I hadnt used my card in two days.  <response>: The location of charges dont matter. Once the CC information is obtained it can be sold or passed to anyone anywhere. Typically, the person stealing the information wont use it themselves. I would alter your usage patterns e.g switch between two or three cards at the usual places. If that new card is leaked then you found the leak.
