Security Essentials is an antivirus program from Microsoft. Security Essentials is free for all Windows XP, Windows Vista and Windows 7 users. Windows 8 to Windows 10 users can use the inbuilt Windows Defender antivirus. Windows XP users are advised that Microsoft no longer provides updates for Security Essentials for Windows XP. Security Essentials provides protection against various malicious software such as spyware, Trojan programs, worms, viruses and other malicious software.

Security Essentials has two scanning modes, quick scan and full scan. Quick scan only checks the common locations where malware is found. A full scan, on the other hand, checks all folders on the system. There is also a custom scan option that allows a user to scan a specific folder or removable storage device.

The settings tab provides a user-friendly interface for customizing and configuring Security Essentials. You can set many options in Security Essentials. You can exclude specific locations and files from scans to speed up scans. You can also exempt specific processes and file types from scans. A useful advanced option is that of creating restore points before quarantining or removing detected malware. In the history tab, you can view all quarantined items or items that you allowed to run on your computer.
