There is a very nice review of Google's software bundle "Google Pack" at winsupersite.com:

• Norton Antivirus 2005: Free, but out of date.
  
• Ad-aware: Free, but no live protection, and out of date.
  
• Gallery Player sample images, yes, but application, no.
  
• Google Earth is cool, sure, but who needs this?
  
• The star of the show: Picasa.
  
• RealPlayer is capable, but wants you to upgrade.
  
• Trillian is a decent IM application.
