Help removing a keylogger
Hey guys,
I am almost certain I have a keylogger on my Mac OS X. I believe I downloaded it some point while downloading music, movies, various files, etc. What makes me believe I have a keylogger is the fact that many of my web accounts passwords are being changed. All the passwords were unique, many associated with different emails and password recovery measures. Furthermore, I added security measures on an account yesterday that required a user to correctly answer 5 recovery questions before accessing the account via a different IP address or computer. This account proved to be hacked into after these security measures were added. I am the sole owned of the machine and administrative installation of a keylogger is not a possiblity. Can anyone help me with what I should be checking my activity monitor for, or further measures of finding and deleting this likely keylogger?
Thank you very much.
