After having various accounts hacked 3 times over the course of about six months I've started to consider the idea that I have had a keylogger installed on my macbook. I know of the person who is doing it, and while I live in BC, Canada, the person who hacked my accounts lives in Washington so it would've had to of come over the internet. In the last instance, I had a hotmail account, facebook, xbox live (through xbox.com I'd assume), website, web host, and email account associated with website stolen within 24 hours. All privacy settings set up, 16 digit password including numbers and letters, and a different password on almost every account. Nevertheless, I lost everything almost in an instance, and again this was the 3rd time. I've scoured through Activity Monitor trying to find something suspicious, but beyond that I don't know a whole lot about Internet security on macs, how can I go about finding out for sure?
