If the end user automatically chooses to remove the "infection", it will nuke Google Chrome and prevent you from reinstalling it. Here's what you need to do to fix the problem:
1. Backup your C:\Documents and Settings\UserName\Local Settings\Application Data\Google\Chrome\ folder
2. Follow the directions to manually remove Google Chrome here: http://www.google.com/support/chrome/bin/answer.py?answer=111899
3. Download and reinstall Google Chrome.
Note: If the MSE/Forefront detects the virus again, make sure you select the “Always Allow” option. Tomorrow, when your definition updates and corrects the false positive issue, you can manually remove this entry from MSE/Forefront.
4. Exit from Google Chrome if it launches
5. Copy the backup folder to its correct location; this restores the bookmarks and settings.
