Microsoft has officially announced the arrival of its eagerly awaited free anti-virus software, Microsoft Security Essentials.

The software giant is keen to ensure that computers are better protected worldwide, and its solution is to release a free application that will be available for everyone.

"Consumers have told us that they want the protection of real-time security software, but that they are confused by trials and renewals and concerned about performance and as a result, too many are unprotected" said Amy Barzdukas, general manager for consumer security at Microsoft.

Won't get in the way

"With Microsoft Security Essentials, consumers can get high quality protection that is easy-to-get, easy-to-use, and won't get in their way."

Available from http://www.microsoft.com/security_essentials the package protects against viruses, spyware and other malware, but Microsoft will continue to offer its paid-for Forefront Client Security for businesses.

TechRadar has already had a hands on review of Microsoft Security Essentials, which has already had a beta release, and it certainly looks well worth installing.

Microsoft Security Essentials is available now.
