So after years of using a PC and running daily antivirus scans and weekly malware scans, you finally decided to switch to a Mac. You have a right feel safe knowing there are currently no viruses attacking Mac OS X (compared to the one million viruses and trojans that affect PCs), but there are still vectors of attacking your Mac through macros in documents and software vulnerabilities in your browser or other applications. Take a minute to review your antivirus options for your Mac.

Microsoft Office has become the standard office application suite for most businesses, government offices, public schools and universities, and even nonprofits. With eight versions of MS Office available to consumers, ranging from $150 to $680 for full versions (not upgrades), and seven bulk licensing options available for organizations, it's a costly and confusing standard to maintain. Free, open source alternatives such as OpenOffice.org, NeoOffice and KOffice can open and edit MS Office files, and offer similar or additional software features without the hefty price tag and confusion. So I ask, why are you still wasting your money on MS Office?

I'm a big geek, and as such, I spend a couple hours each month auditing my Mac: I free up disk space by deleting large files, remove applications I no longer use, and update those I do. Here, I'll review several utilities to help you perform such an audit quickly and with an economy of mouse clicks. Oh, and don't worry if you only do it once a year (like I said, I'm a big geek).
