    Hello there

    Since I'm getting quite suspicious about everything concerning internet I'd like to protect my mac as good as possible. However, there are so many different programs that I – who doesn't really know anything about mac – can't decide which one to use. I started with Onyx yesterday, but this is how far I could go.
    So, if you have any recommendation I would be pleased.

    There really isn't much else you need to do. A few other things you can do is disable Java in your browser and always download those software updates from Apple.

    OnyX is a utility for performing various maintenance tasks. It doesn't provide "protection" against internet risks.

    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. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
    1. Make sure your built-in Mac firewall is enabled in System Preferences > Security > Firewall

    2. Uncheck "Open "safe" files after downloading" in Safari > Preferences > General

    3. Disable Java in your browser (Safari, Chrome, Firefox). This will protect you from malware that exploits Java in your browser, including the recent Flashback trojan. Leave Java disabled until you visit a trusted site that requires it, then re-enable only for the duration of your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)

    4. Change your DNS servers to OpenDNS servers by reading this.

    5. Be careful to only install software from trusted, reputable sites. Never install pirated software. If you're not sure about an app, ask in this forum before installing.

    6. Never let someone else have access to install anything on your Mac.

    7. Don't open files that you receive from unknown or untrusted sources.

    8. For added security, make sure all network, email, financial and other important passwords are long and complex, including upper and lower case letters, numbers and special characters.

    9. Always keep your Mac and application software updated. Use Software Update for your Mac software. For other software, it's safer to get updates from the developer's site or from the menu item "Check for updates", rather than installing from any notification window that pops up while you're surfing the web.
    That's all you need to do to keep your Mac completely free of any Mac OS X malware that has ever been released into the wild. You don't need any 3rd party software to keep your Mac secure.

    My firewall was not activated. No idea how this happened.

    Thank you very much for your help.

    The firewall is not enabled, by default, on new Macs. You have to enable it.

    You guys talk to people nicely!


    Block incoming and enable stealth mode. Apple usually did not turn the firewall by default!
