You don't need any 3rd party antivirus app to keep your Mac malware-free. 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.one more question: does this mean i have a virus that could potentially be doing MORE harm on my computer right now?
i realized the voice suddenly "appeared" after a friend of mine sent me an email with a link (the following one) - DON'T CLICK ON IT OR YOU MAY HAVE A VIRUS TOO.
i am so stupid - i know better than to open attachments unless i know what they are, but this one got me b/c it looked like a link (underlined in the email) vs. a file (an icon) in the email. also, i thought macs were impervious to viruses - silly me!!??
And if you have a master password for the computer, change that, too. Because a master password can be used to reset the passwords on other accounts. Google search terms: mac os master password.Much more likely is that you have friend/room-mate/sibling who had fun messing around with your Mac. Put a password on your log-in account. If you already have one, change it.
