These programs are useful Media players for your Mac. They're all freeware, and I use them on my own personal Macs. Click on each link to download the installer:
VLC Video Player - It plays some Windows based audio and video files
Flip 4 Mac - This is a plug-in that allows Quicktime to play WMV and AVI files
Neo Office - Open Source MS Office Alternative - FREE!
Other rules to remember: If you don't recognize the person or company who sent you an email, or that pops up on a web page, do not click on it.
If you get an email notification from your bank or other institution that looks legitimate, DO NOT click the email link to get to the institution. Instead, go to the company's homepage and either find their support page, or call their phone number to ask for assistance.
