Windows Defender (32-bit)

Windows Defender is a comprehensive security utility built and maintained directly by Microsoft Corporation, the creators of the Windows operating system. Its primary purpose is to observe the activated applications for malicious behavior and monitor all the files present on your local storage, portable storage accessories, and the files that are being downloaded from the internet.

By monitoring all your interactions with local and remote files, and especially with executable applications, Windows Defenders serves each user of Windows OS as the first line of defense against the malicious software that can invade your privacy, steal your private, work and sensitive data, corrupt your OS or even lead to a total lockdown of OS capabilities.

To stay ahead of the ingenious attempts of the hacker community, Microsoft Defender Offline is built to always run in the background of your PC and update itself with the latest “definition” upgrades that can tell it how to recognize all forms of malicious software. To provide the best security possible, this app is automatically configured to perform its duty as best as possible, not demanding from users any permissions, activations, configurations, or any other input. It simply always runs in the background, taking a minimal amount of hardware resources. It automatically scans all active processes giving you reliable real-time protection, protects your PC from all forms of ransomware software, constantly remains in touch with cloud servers that distribute new anti-virus definitions and threat behavior detection algorithms, and much more.

All of the features of this widely popular security utility are accessible inside Microsoft Defender Security Center which is accessible directly from your OS Control Panel. There you can see the current security status of your PC, see if all protection modules are activated and running, set the specific behavior regarding internet Firewall service, security-related app and browser behaviors, find your lost or stolen device, and even set up and monitor Family options for household devices that are used by children (including screen-time habits, enhanced online protection, and much more).

Originally released in 2005 as a 100% FREE standalone security solution for Windows XP and Windows 2000, this application has managed to grow with incredible pace, becoming an official built-in anti-spyware component in Windows 7 and Windows Vista. On Windows 10/Windows 11 it is also known as Windows Defender Antivirus.
