Google updated its Google Pack to include the Norton Security Scan from Symantec and PC Tools Doctor Starter Edition:
The first program detects and removes viruses, and PC Tools' Spyware Doctor Starter Edition is a top-rated anti-spyware utility. Both are free and include automatic protection updates with no paid subscription required.
We've also substantially updated our screensaver. Now you can turn your computer into a digital picture frame that displays pictures from photo feeds—continuously updated streams of photos from the web. Many of your favorite photo-sharing sites support them already, so it's easy to keep in touch with your friends and family this way.
