    Every time I open safari I see this message "An error occurred while attempting to initialize the value for cmi.core.lesson_status to incomplete" if I click OK it just keeps reopening. I can't open safari preferences to reset the cache, etc... because of this message and reseting my computer did not solve the issue either. The only way to stop this is by force quitting.

    The core.lesson it is referring to is the from the site I had open right when this started occuring, this is a trusted website so I do not believe there was a virus there causing this. Any advice would be much appreciated.

    Delete the /Users/yourusername/Library/Preferences/ file, then relaunch Safari.
    You're right, since no Mac OS X viruses exist. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. You cannot infect your Mac simply by visiting a website, unzipping a file, opening an email attachment or joining a network. The only malware in the wild that can affect Mac OS X is a handful of trojans, which cannot infect your Mac unless you actively install them, and they can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
