    Hey Guys! First post... just curious - do you guys know if we can use these two programs together or do I need to uninstall one? I know you can't use two antivirus programs but I'm not sure if this applies since internet barrier is a different type of program. Also, Sophos is business grade protection as their website says.

    Thank you

    Uninstall both. 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.
    Sophos should be avoided, as it could actually increase your Mac's vulnerability, as described here and here.

    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. Uncheck "Enable Java" in Safari > Preferences > Security. Leave this unchecked until you visit a trusted site that requires Java, then re-enable only for your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)

    4. Check your DNS settings 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 physical access to install anything on your Mac.

    7. 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 virus, trojan, spyware, keylogger, or other malware. You don't need any 3rd party software to keep your Mac secure.

    Thanks for the replies... At the risk of sounding a little mac noobish - how do I check to see if anything malicious is installed on my computer? I noticed there are lots of users and uids on my mac. I know many are system users like the user "nobody". I may have installed things in the past which could have been something malicious but Im not sure. How do i check for key loggers/hackers/malware/etc without an antivirus?

    You can scan once with ClamXav, which isn't a resource hog, detects both Mac and Windows malware and doesn't run with elevated privileges... and it's free. ClamXav has a Sentry feature which, if enabled, will use significant system resources to constantly scan. Disable the Sentry feature. You don't need it. Also, when you first install ClamXav, as with many antivirus apps, it may perform an initial full system scan, which will consume resources. After that, as long as you practice safe computing using the tips I posted, you won't need to worry about scanning for malware. By the way, make sure you completely remove all components of Sophos and Intego. The most effective method for complete app removal is manual deletion:
