About This Software
Microsoft Security Essentials relies on regular definition updates to detect the latest threats. Manual updates become necessary when your internet connection is unstable, when you need to update multiple computers offline, or when automatic updates aren't functioning properly. The official Microsoft website provides the latest definition files that can be downloaded and transferred to your computer for installation. These updates contain information about new viruses, spyware, and other malicious software that your antivirus needs to recognize and block.
