i just recently bought a macbook pro 2011 (13inch) and i really don't know much about OSX.
about 2 days later. i found out i had a Keylogger virus on my PC and compromised alot of my game accounts.
now i understand when you want to install anything on the mac it requires ur login password. but is it possible for a mac keylogger malware to install without permission?
Use a anti virus called ClamXva which is free and I have used it over 1 year with no problem at all.It is especially for Macs.Good Luck marv
