Microsoft Security Essentials provides robust protection for both residential and business computers against spyware, phishing, malware, and hacking attempts.

For any Microsoft product, Security Essentials is completely free to download. It is consistently kept up to date by the Microsoft team for all valid Windows products.

The user friendly, simple interface uses intuitive red, green, and yellow colors to indicate the current security of your personal computer. The anti-viral software will alert you the moment it detects you've clicked on a risky link, download file, or advertisement.

During regular use, the software continuously runs in the background to scan for security threats. It's a real time software that doesn't cause excessive system lags or interruptions.

When your computer is idle, Security Essentials will run deeper scans of your system's directory tree in order to root out any malicious processes.

Microsoft Security Essentials is available for any Windows Vista or 7.0 computer. Additionally, your system should have a processing speed of 1.0 GHz in order to adequately run the software. One gigabyte of RAM must be available for successful installation.

Unlike other anti-viral software, Security Essentials only requires 200 megabytes of hard disk space, which is more than half that of competitor products. It's the ideal solution for systems that are lacking on disk space.

Before installation, it's recommended that you first uninstall any anti-virus software currently on your system. Previous anti-viral software may conflict with the software.
