Microsoft Security Essentials Free Download


Microsoft Security Essentials provides real-time protection for your home or small business PC that guards against viruses, spyware, and other malicious software.

Microsoft Security Essentials is a free download from Microsoft that is simple to install, easy to use, and is automatically updated to protect your PC with the latest technology.
Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want without interruptions or long computer wait times.
Before installing Microsoft Security Essentials, we recommend that you uninstall other antivirus software already running on your PC. Running more than one antivirus program at the same time can potentially cause conflicts that affect PC performance.

System Requirements

Windows 7
Windows Vista

Windows 8 does not requires this. Windows 8 comes with Windows Defender, which has been improved in Windows 8 to provide the same level of malware protection as Microsoft Security Essentials.
