In February 2006, Google released a new feature for their beta desktop search application that allows users to search their files, documents, emails, chat logs, and web history from any computer. This application makes searching your computer similar to searching on the Internet.
The new feature, "Search Across Computers," poses a serious risk to your privacy. If you use this feature, any files that you access using Google Desktop will be copied and stored on Google's servers. This makes your personal information much more vulnerable to hackers. If your account with Google Desktop is not carefully configured, you can unknowingly transmit copies of your data that are stored on Google's servers. Simply uninstalling this program can leave your personal data on Google's servers for up to 30 days, plenty of time to be hacked.
You should seriously consider the risk posed to your confidential information by this application before downloading it. If you currently use this program and are concerned about the security of your information, you can manually purge all of your data from Google's servers.
