Microsoft has introduced its new free Windows security suite ‘Security Essentials 2’ that the company says features a new malware detection engine and closer integration with Windows Firewall and Internet Explorer, with the Vole also showing performance improvements.

The new security suite supports machines running Windows XP Service Pack 2 and Windows Vista and Windows 7, though not all features are enabled on Windows XP, according to theinquirer.net.

Microsoft is pitching Security Essentials 2 at consumers and small businesses with up to ten machines, while for larger organisations the Vole has updated its Forefront Endpoint Protection security software, which includes real-time server monitoring.

Microsoft is offering the new security suite for free to individuals and small businesses, although medium-sized and larger businesses that want Forefront will have to pay for it.

The medium-sized and larger businesses can alternately move over to Linux, where most software including a lot of security software is free, and they can opt to pay for support, the website reported.
