I installed a trial version of MacScan yesterday, and it found a key logger called KeyBag 1.8 I googled KeyBag and found it is an application that you can buy to keep logs on employees or family members computers. It also seems that popular opinion is that the only way it can get on your machine is if someone physically installs it. Well, that was not what happened to me. There are only two people in our house, and neither of us installed it, so it can only have come in an email, a torrent, or a software download, and then self installed. Up until yesterday, I have felt pretty secure with my Mac and running Shields Up occasionally, and MacScan even less often. That has now changed. ClamX is now in the dock set up to update & scan daily in the wee small hours, with it's Sentry configured to check everything coming in. MacScan will be run very regularly from now on. Luckily for me, my bank is smart, and I enter our pin by clicking on keyboard on the screen, so key logger proof, but I do use my credit card online on the odd occasion, so I will be entering to CC number now by copy & paste method from a secure .doc file. (Also key logger proof) I would like to know if anyone else has had a key logger or similar just show up out of the blue?
