Google Copies Your Hard Drive - Government Smiles in Anticipation

Consumers Should Not Use New Google Desktop

San Francisco - Google today announced a new "feature" of its Google Desktop software that greatly increases the risk to consumer privacy. If a consumer chooses to use it, the new "Search Across Computers" feature will store copies of the user's Word documents, PDFs, spreadsheets and other text-based documents on Google's own servers, to enable searching from any one of the user's computers. EFF urges consumers not to use this feature, because it will make their personal data more vulnerable to subpoenas from the government and possibly private litigants, while providing a convenient one-stop-shop for hackers who've obtained a user's Google password.

The Belarc Advisor builds a detailed profile of your installed software and hardware, missing Microsoft hotfixes, anti-virus status, CIS (Center for Internet Security) benchmarks, and displays the results in your Web browser. All of your PC profile information is kept private on your PC and is not sent to any web server.
