When you install any Google software product, such as the Chrome browser or Google Earth, Google Installer will ask your firewall to let it access the Internet many times a day to check for software updates.
It's not that Google Installer is doing anything wrong ... but most people wonder why it has to check for updates constantly?! Why waste the bandwidth and system resources?
According to Google, the Google Installer "keeps your Google software up to date. If this task is disabled or stopped, your Google software will not be kept up to date, meaning security vulnerabilities that may arise cannot be fixed and features may not work. This task uninstalls itself when there is no Google software using it."
In July of 2009, Google announced that the Google Installer (Google Update) would no longer run continuously but would be managed by Windows Task Scheduler (https://opensource.googleblog.com/2009/07/google-update-regularly-scheduled.html).
This is GOOD NEWS. You can easily change how often Google Installer accesses the Internet to look for updates via Windows Task Scheduler (http://www.google.com/support/forum/p/Chrome/thread?tid=7ab51d2e6b9da08a&hl=en). Then you can tell your Firewall to "Always Allow" and be done with it!
The following image shows four Google tasks in the Task Scheduler window. You may have more or less, but use this as a guide.

To change a task's schedule on your PC, follow the steps below:
- Access the Windows Task Scheduler by clicking Start | Programs | Accessories | System Tools | Scheduled Tasks (or Task Scheduler)
- Make the window as wide as possible. Notice the current schedule shown in the second column
- Right-click on the first Google Installer task and click Properties
- Click the "Schedule" tab
- If the task is scheduled to run at "user logon" - don't change it
- If the task is scheduled to run Daily, change the frequency to Weekly, at User Logon, or other option. If Weekly, make sure only one day is checked in the "Schedule Task Weekly" box below. Change the time if you wish
- Click the "Advanced" button if available. Remove the checkmark next to "Repeat task" and click OK
Repeat steps 3 through 7 for the remaining Google Update tasks. Then click Apply and click OK. Exit out of the "Scheduled Tasks" window.
Now the Google Update program should only request access to the Internet at the times you scheduled for the tasks. And once you feel confident that it is working correctly, you can tell your firewall to "Always Allow" and you won't be bothered again.
Cheers!
