Bought a hackintosh, may be infected by keylogger
Okay so I believe my mother may have bought an infected hackintosh. It is a dell inspiron v10 with Snow Leopard installed.
Basically she bought it from someone she believed to be a trusted seller, I used it to purchase xcode, we later found the same card to have been used for two transactions in Mexico. This was the only digital purchase made on the card, on this particular laptop. Mexico also happens to be somewhat close to the location we bought it from.
I hear that remote viral infections are rare on macs, and the real danger is in self-installed viruses which are hard to detect. This would make perfect sense in this situation, and I'm wondering if anyone has any advice on how to look for it or even where I should ask for help. Any advice would that can get me working on this laptop securely would be greatly appreciated. I intend to change my apple account password and all other passwords as well. Thank you for your time.
