    So i dont know what I am doing.

    I've had my Mac Pro for 2+ years and its getting super slow. I have never updated/ installed any of the new operating systems. Im still running Mac OS X 10.5.8. I've already backed up all my files on an external hard drive. What do i need to do next? A complete set of dummy proof instructions would be a treat!

    Thanks

    You don't necessarily need to reformat to improve performance. I've never done it in 4+ years and my MBP still runs as fast as day one.

    What kind of issues are you having? It's not a virus. 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. While you may elect to use it, 3rd party antivirus software is not required to keep your Mac malware-free.

    It's not infected. There are no viruses that can infect your Mac. Mac OS X isn't Windows, and you don't have to do the same things on your Mac that you did on your PC. Have you gone through the performance tips I posted?
