Microsoft Security Essentials - Free Antivirus
Introducing Microsoft Security Essentials
Microsoft Security Essentials (MSE) is a complimentary software designed to deliver robust, real-time protection against viruses and other malicious software that can compromise your personal computer. This article will explore its performance capabilities and the security features it provides.
MSE represents Microsoft’s latest offering in anti-malware protection, succeeding their previously subscription-based utility, One Care. Having transitioned beyond its beta phase, version 1.0 was officially released to the public recently.
Core Functionality and Installation
Similar to its beta iteration, this version offers continuous, real-time protection while operating discreetly in the background. The user interface remains largely unchanged from the beta version.
Prior to installation, ensure that no other antivirus or anti-spyware programs are actively running on your system. However, Windows Defender does not need to be manually disabled, as MSE will manage its operation automatically.
To proceed with installation and utilize Security Essentials, you must first validate your copy of Windows.
User Interface and Operation
The interface is characterized by its simplicity and ease of navigation. Upon initial installation, the software immediately updates its virus definitions.
Subsequently, it automatically updates itself in the background, establishing a truly “set it and forget it” operational model.
Once the virus definition database is current, the system status is indicated by a green icon.
The application features four primary tabs, providing control over various functions.
Configuration and Settings
Within the Settings section, you can define the actions Microsoft Security Essentials should take in response to threats, categorized by their severity level.
Real-time protection is enabled by default, though it can be disabled if desired. This real-time scanning feature is designed to minimize impact on system resources and avoid slowing down other processes.
A green icon in the notification area visually confirms that your system is under protection.
Scanning and Threat Detection
During a manual scan, progress is displayed, along with an estimated completion time. Scan durations will vary depending on the number of files and the performance of your hardware.
The software functions similarly to other antivirus applications, allowing you to scan individual files.
When a threat is identified, a red alert appears in the Notification Area, prompting you to address the issue immediately based on the recommended actions or to review detailed information about the detected threat.
Threat Details and Remediation
Detailed information regarding each threat is readily available. Within the details screen, you have the option to modify the recommended action and initiate cleaning procedures.
Real-World Performance
During testing, an attempt to download an infected file was blocked by MSE, preventing the download unless explicitly overridden. This proactive measure is beneficial in preventing users from inadvertently ignoring warnings and installing malicious software.
System Compatibility and Resource Usage
The software was tested on the 32-bit version of Windows 7 Home Premium, but is also compatible with Windows XP and Vista. It is designed to be lightweight and operate quietly, minimizing interruptions with frequent notifications.
However, it will alert you when a significant threat is detected, displaying a red alert to inform you of the malware and prompt you to take appropriate action.
Having a free, user-friendly, and effective anti-malware utility is a significant advantage. While Microsoft’s security solutions haven't always been leading, this offering appears to be a successful implementation. Download Microsoft Security Essentials
