Microsoft's free anti-virus and malware protection software called Microsoft Security Essentials is now available for Windows XP, Vista and Windows 7. Microsoft Security Essentials is designed to run quietly in the background alerting users only when there is an action for them to take. It also limits CPU and memory usage, resulting in less impact on the tasks consumers perform every day such as opening documents or browser windows or loading search results, even on older or less powerful PCs. Microsoft Security Essentials uses real-time protection to help prevent PCs from becoming infected, and it is the first Microsoft security product to make use of the company’s new Dynamic Signature Service, a technology that helps ensure users stay protected by the most current virus definitions available without having to wait for the next scheduled download.
Microsoft Security Essentials will be available in eight languages and 19 countries including Australia, Austria, Belgium, Brazil, Canada, France, Germany, Ireland, Israel, Italy, Japan, Mexico, the Netherlands, New Zealand, Singapore, Spain, Switzerland, the United Kingdom and the United States.
