Hewlett-Packard has launched a new desktop PC family for power business users that it said offers added security and power-saving features.

The HP Compaq dc7900 Business Desktop series machines come in three different styles - an ultra-slim desktop, a small form factor or a convertible minitower.

The new desktops are slated to be available by the end of September with a starting price of $599 (£341).

The desktops run the HP Firefox Virtual Browser, which was jointly developed with the Mozilla Foundation and Symantec. The browser operates in a virtual run-time environment, which means that everything from cookies to downloads are squirreled away in sandbox. That sandbox keeps downloads from touching everything else in the system and can be cleaned out with a click of the mouse.

"This preventative measure potentially limits the need to conduct a scan, repair and reinstall of applications and security settings," HP said in a statement.

The new systems include HP's ProtectTools, which allow users to personally adjust levels of security protection. The dc7900 line also includes a Privacy Manager for securely exchanging emails, and a File Sanitizer, which enables users to remove data before disposing of their computer.

The dc7900 series also uses HP Power Manager, a technology designed to enable users to personalise their power settings so they can vary the mix of performance and power conservation.

The new power systems come out a month after HP went after business travellers with the release of three new ultraportable laptops.
