Windows users can now download Microsoft’s antivirus software called Security Essentials. It protects against malicious files such as Trojan horses and worms.

The beta version was released in June on some countries such as U.S., Brazil, and China.

The sofware can run on XP, Vista, and 7 machines. It is not meant to compete with other antivirus software such as the ones from McAfee and Symantec.
