Microsoft Security Essentials Review

Microsoft Security Essentials

Microsoft Security Essentials is a free antivirus program that protects against viruses, spyware, and rootkits. Designed to be easy-to-use without interfering with other applications or slowing network performance, this antimalware solution delivers outstanding protection without slowing performance or interfering with productivity.

Real-time protection with antimalware engines and rootkit detection capabilities; however, this antivirus program lacks many of the more advanced options offered by other antivirus solutions.


Microsoft Security Essentials anti-virus program is an excellent way to safeguard your PC against malware, working quickly and efficiently to ensure its safety. Plus, its intuitive user interface makes managing it effortless – perfect for small businesses in search of quality cybersecurity protection at an economical price!

Microsoft Security Essentials employs Microsoft’s own cybersecurity technology to defend against cyberattacks. With real-time protection against malware and regular system scans to make sure systems are safe, it provides effective real-time protection compared with its counterparts, yet doesn’t include firewall protection and central management capabilities – two essential components for protecting larger networks.

This program serves a primary function: eliminating viruses and spyware from your PC. With an impressive success rate and free availability for Windows operating system users, its primary goal is removing malware. It boasts an easy-to-use interface and features such as an “at a glance” scan history tab; scheduling scans; toggling default actions upon detection; creating whitelists of excluded files/folders and even decompressing archives to detect potentially hazardous files evading antivirus solutions – making this an invaluable asset to anyone’s PC!

Dennis Technology’s test scoring system rewards programs that successfully detect and defend against malware intrusion while penalizing false positives; in these tests, MSE excelled, only losing one point out of five possible points available to it.

Microsoft has long attempted to develop a comprehensive antivirus solution, and their most recent offering is Security Essentials: an extremely lightweight yet fast-performing alternative that’s free for consumers and can protect up to 10 computers within the home or office; small businesses may use it but only up to 10 computers before subscribing for Microsoft Forefront Endpoint Protection tools instead.

Easy to use

Microsoft Security Essentials (MSE) is a user-friendly free antivirus program, making installation and use effortless. MSE provides constant virus protection against malware attacks on your PC by running quick scans in common areas where viruses hide as well as full and custom scans based on user preference. MSE updates its virus definitions automatically so you know your computer remains secure at all times.

MSE can help protect against infections by creating System Restore point backups that will enable easy data restoration in case of an outbreak, detect and remove malware using dynamic signatures that identify suspicious programs before they run, as well as protect against unwanted spyware running in your privacy. Its easy setup requires minimal system resources; in fact, MSE can even be installed onto USB drives for convenient portability.

MSE stands out from McAfee and Norton by being completely free-of-charge and without subscription requirements to access updates, but does not include a firewall, which could prove detrimental if used on multiple devices simultaneously. Furthermore, running in the background could potentially cause performance issues for some users.

MSE is an excellent solution for older Windows systems, as its installation process is straightforward and uses minimal system resources. Its virus detection rates are some of the highest available, while it also boasts device optimization features and lightweight performance across a wide variety of hardware – making it suitable for home computers as well.

Microsoft officially discontinued support for XP on April 8th, meaning MSE won’t receive any further definitions or signature updates after that date. This leaves XP users open to further infections and malware attacks and may lead to upgrading to a more modern operating system like 8.1 or 10 which already include Windows Defender protection – it may interfere with each other and reduce performance on your system if more than one antivirus program runs simultaneously.

Compatible with Windows XP

Microsoft Security Essentials protects your Windows PC against viruses, Trojans, worms, spyware and other forms of malicious software (malware) without slowing down or restricting functionality of your computer. With real-time protection ready to block malware attacks at any time – Microsoft Security Essentials protects against cyber security threats 24/7/365 with real-time protection always ready. Alerting you of suspicious programs or files when they are detected, and giving you options on how to handle them (quarantine, ignore or remove). Furthermore, virus definitions are automatically updated. Your program(s) that have been approved are monitored as well, to make sure they do not make unanticipated network connections or modify core elements of your operating system. Dynamic Signature Technology of this antivirus prevents malicious software from bypassing security protocols by imitating legitimate programs and asking the antivirus to test them for behaviors they don’t belong to, such as making memory and registry scans to identify and block any unusual activity, and by using advanced techniques for rootkit detection and blockage that may otherwise be difficult to identify.

This free antivirus program is easy to set up and use efficiently in the background, keeping its security signatures current. Ideal for home users, small businesses and larger enterprises alike; though its feature set might not match some competitors it provides solid basic protection at no additional cost.

Microsoft announced last year that Windows XP support had come to an end; however, antimalware signature and engine updates would still be made available for one more year after support ceased. Unfortunately this promise ended yesterday with MSE version 4.5 no longer compatible with XP operating systems.

Yet there are XP users who remain faithful and wish to stick with this operating system for some time yet. If that describes you, consider signing up for an antivirus program designed specifically for XP – you’ll find many available online.

Note that only installing one antivirus program at a time. Installing multiple antivirus programs simultaneously may create conflicts and reduce computer performance, as well as making updates harder to come by. Finally, be sure to update your definitions regularly so you can protect against new threats that emerge on a regular basis.

Doesn’t work on Windows 7

Microsoft Security Essentials is a free antivirus software program designed to defend against viruses, spyware and other forms of malicious software. With real-time protection running in the background and easy installation process it keeps up with modern technologies to keep you protected while you work. A green checkmark indicates your PC is protected and ready to go for use.

Microsoft also offers other free anti-malware programs, including Windows Defender. These software products boast more robust features than MSE, such as cloud storage and password management – perfect for accessing sensitive information remotely from other computers. However, to remain using MSE on your own computer, make sure that its operating system version remains up-to-date.

MSE provides more than just anti-virus capabilities; in addition to basic firewalling and parental controls. Restore checkpoints help prevent data loss during malware attacks; it has a sandbox feature to isolate new files before running them; it shares information regarding detected malware with SpyNet which monitors suspicious activities and submits reports directly to authorities; MSE shares malware detections via social networking features like SpyNet for further review.

MSE remains an invaluable piece of software, offering on-access protection at no cost to its users. As an effective alternative to antivirus solutions like McAfee and Norton which charge for their services and require updates each year, MSE should continue providing valuable protection despite its deficiencies; however, new versions won’t be released after 4.10. To stay secure in the interim users should download and install any available virus definitions from various virus definition providers.

Microsoft Security Essentials can be downloaded free from their website. Designed for both Windows 7 and Vista computers, this program requires at least 200MB hard disk space and 1GB RAM – in addition to having a VGA display with 800×600 resolution or greater – for optimal use. Once your computer meets all these criteria, an installer will scan it and begin the installation process; once complete, a verification step must be performed using valid login and password details before closing down your session.
