Windows Live OneCare security site is to be pre-installed by 11 computer original equipment manufacturers.

The service, which Microsoft says offers an all-in-one security and malware protection suite, is said to automate and simplify PC management and performance. It is aimed at consumers and small businesses.

It checks for viruses and removes them, eradicates junk from the hard disk and makes computers run more smoothly.

Hardware providers MDG Computers Canada, LEO Gesellschaft fur Computer & Kommunikation, Wortmann, Olidata, Hyrican Informationsysteme, Sotec Company, TICNova Quality Team, Sony Corporation of America and Toshiba Asia Pacific are among those who have signed up to the move.

Select new PCs across Europe, North America and Asia will have the software installed on a trial subscription basis.

"Consumers have told us they want an easier, more automated experience with the security and overall health of their PCs," said Amy Barzdukas, senior director of Windows Live OneCare at Microsoft.

"Through these alliances, we are addressing the needs of new PC users who want to easily protect, backup and maintain their new PC right out of the box."
