The launch of Security Essentials sees Microsoft attempting to give Windows users an all-encompassing anti-virus, anti-spyware and anti-malware application, for free.

The interface is clear and intuitive, with simple options to scan for viruses or back up and restore files. The health bar lets you know your security status and will guide you through the necessary steps when problems arise.

Microsoft claims that 70 per cent of consumers do not have anti-virus software or do not keep it updated, so Essentials is specifically aimed at inexperienced users who may not have the technical know-how or time to manage a computer on a daily basis.

This version Microsoft Security Essentials will only work in genuine versions of Windows and is for personal-use only.
