1. Overview of AVG and Microsoft Security Essentials

To begin, it’s essential to understand the history and background of both antivirus solutions. This will give you an insight into their evolution and how they have come to be trusted by millions of users around the world.
AVG Overview
AVG Technologies is a globally recognised cybersecurity company known for its comprehensive antivirus and security products. Founded in 1991 and based in the Czech Republic, AVG has evolved into one of the leading antivirus providers, offering both free and paid versions of its software. AVG antivirus is known for its robust real-time protection, malware scanning, and excellent customer support. In addition to basic virus protection, AVG also provides features like ransomware protection, email security, and a secure VPN for privacy-conscious users.
One of the standout features of AVG is its user-friendly interface, which makes it accessible for both beginners and advanced users. Additionally, AVG frequently ranks high in independent antivirus tests for its malware detection and removal capabilities.
Microsoft Security Essentials Overview
Microsoft Security Essentials (MSE) was a free antivirus software released by Microsoft in 2009. It was designed to provide basic protection for Windows users against viruses, spyware, and other malicious software. MSE was later integrated into Windows 8 as Windows Defender, and its standalone version was phased out in 2013. However, it remains relevant for users on older versions of Windows, such as Windows 7.
Microsoft Security Essentials was known for its simplicity, offering basic protection without any complicated features or advanced settings. It was a lightweight solution that provided fundamental antivirus protection but lacked some of the advanced features and real-time monitoring capabilities that users may expect from other premium antivirus software.
2. Key Features

The core functionality of any antivirus software is its ability to detect, block, and remove malicious software. However, additional features can make the software more robust and versatile. Let’s take a closer look at the features offered by both AVG and Microsoft Security Essentials.
AVG Features
AVG offers a comprehensive range of features, even in its free version. The key features include:
Real-Time Protection
AVG provides continuous, real-time protection against viruses, malware, spyware, and other forms of malicious software. It constantly scans files as they are opened or executed, ensuring that threats are detected and blocked before they can cause harm.
Ransomware Protection
AVG’s paid versions include a dedicated ransomware shield, which protects against ransomware attacks. This feature monitors any suspicious behaviour from programs attempting to encrypt files and blocks them before they can carry out their attacks.
Web & Email Protection
AVG also provides strong protection against online threats through its web protection features. It blocks access to unsafe websites and prevents malicious downloads. The email protection system scans incoming and outgoing emails for potential threats, such as viruses or phishing scams.
File Shredder
AVG includes a file shredder in its software, which securely deletes files to prevent them from being recovered by third parties. This is particularly useful when you need to dispose of sensitive documents securely.
Privacy Protection
AVG’s paid versions come with privacy features like a VPN, which encrypts your internet connection and hides your IP address to ensure that your browsing activities remain private.
Advanced Scanning
AVG performs full system scans, targeted scans, and custom scans to detect malicious files and software on your device. The software’s heuristic scanning technology allows it to detect emerging threats based on their behaviour.
Microsoft Security Essentials Features
Microsoft Security Essentials (MSE) was relatively basic in terms of its features, as it was designed to provide fundamental protection for everyday users. The key features of MSE include:
Basic Antivirus Protection
MSE offered core antivirus protection, detecting and blocking viruses, malware, spyware, and other threats. It scanned files and programs in real time to prevent infections before they could take root.
Scheduled Scans
Microsoft Security Essentials allowed users to schedule system scans for specific times. Users could choose between quick scans, full scans, or custom scans to identify potential threats.
Automatic Updates
MSE was set up to automatically download updates for virus definitions and software improvements. This ensured that the software could effectively handle new threats as they emerged.
Simple User Interface
One of the defining characteristics of MSE was its simplicity. The interface was straightforward, with only essential settings available. This made it an ideal solution for users who were looking for basic protection without complex features or options.
Low Resource Usage
MSE was designed to be lightweight, with a low impact on system resources. It ran quietly in the background without significantly slowing down the device.
While MSE was adequate for basic protection, it lacked many of the advanced features that are commonly found in modern antivirus software, such as ransomware protection, a firewall, or a VPN.
3. Performance and System Impact

Performance is a critical factor when choosing antivirus software, as you don’t want the software to significantly slow down your system or use excessive resources. Let’s compare the performance and system impact of both AVG and Microsoft Security Essentials.
AVG Performance
AVG is generally known for its strong performance, and it has made significant improvements in recent years to reduce the impact on system resources. Users typically report that AVG runs smoothly without noticeable slowdowns, even when performing full system scans. AVG’s real-time protection is efficient, with minimal impact on performance during regular usage. However, the system may experience some slowdowns during intensive tasks like full system scans or software updates.
AVG offers an optimised experience, ensuring that its protection doesn’t interfere too much with the overall system performance. Additionally, it performs well in independent antivirus tests, often scoring highly for its malware detection and removal capabilities.
Microsoft Security Essentials Performance
Microsoft Security Essentials was designed to have minimal impact on system performance, which made it popular among users who needed a lightweight solution. MSE ran quietly in the background without slowing down the computer during regular use. However, like AVG, MSE could cause some slowdowns during system scans, especially if the scan was set to examine the entire hard drive.
One downside to Microsoft Security Essentials is that, compared to modern antivirus software, it lacked the same optimisation in terms of real-time protection and efficiency. As a result, users may notice slower system speeds and less effective protection when using older versions of MSE.
4. Pricing

Pricing is an important consideration for many users when selecting antivirus software. Some people prefer free solutions, while others are willing to pay for advanced features and additional security.
AVG Pricing
AVG offers a free version of its antivirus software that provides basic protection against malware, viruses, and other threats. However, for more comprehensive protection, users can opt for one of the premium versions. The key paid options are:
- AVG Internet Security: £39.99 per year for 1 device.
- AVG Ultimate: £59.99 per year for 1 device. This includes AVG Internet Security along with the AVG VPN and AVG TuneUp to enhance system performance and maintain privacy.
AVG offers multi-device plans at a discounted rate, making it an affordable solution for families or small businesses that need to protect multiple devices.
Microsoft Security Essentials Pricing
One of the significant advantages of Microsoft Security Essentials was its price: it was completely free. Microsoft offered MSE as a no-cost solution for users running older versions of Windows, such as Windows 7. Unfortunately, MSE is no longer available for new installations, as Microsoft now provides built-in antivirus protection through Windows Defender for Windows 8 and later.
While MSE was free, it lacked many of the advanced features that modern antivirus software offers. For users on Windows 7, Microsoft Security Essentials was an affordable solution, but it is now obsolete in favour of newer security tools.
5. Customer Support
Access to customer support can make a significant difference when troubleshooting issues or resolving technical problems with antivirus software. Let’s compare the customer support offerings of AVG and Microsoft Security Essentials.
AVG Support
AVG offers a range of customer support options, including:
- 24/7 live chat support for premium users.
- Email support for all users.
- Extensive knowledge base and community forums for self-help.
AVG’s support team is known for being responsive and helpful, though some users have reported slow response times during peak periods. For premium customers, AVG provides more personalised support options, including phone support for urgent issues.
Microsoft Security Essentials Support
Since Microsoft Security Essentials is no longer actively supported, the customer support options for MSE are limited. Users of Windows 7 could access support through the Windows support centre, which offered troubleshooting guides and a community forum. However, Microsoft no longer provides direct support for MSE, as it has been replaced by Windows Defender on newer versions of Windows.
For users who still rely on MSE on Windows 7, they will have to seek help from community forums or third-party support providers, as official support from Microsoft is no longer available.
6. Conclusion

Both AVG and Microsoft Security Essentials offer a degree of protection against malware and other threats. However, there are significant differences between the two solutions.
AVG stands out as a feature-rich antivirus solution, offering real-time protection, ransomware shields, web security, and privacy tools such as a VPN. Its paid plans are affordable and come with additional features that enhance system performance and protect user data. AVG’s performance is solid, and it has a minimal impact on system resources during daily use.
On the other hand, Microsoft Security Essentials was a basic antivirus tool designed for older versions of Windows, offering fundamental protection without the advanced features found in modern antivirus solutions. Although it was lightweight and easy to use, it is no longer supported, and its features are outdated compared to the latest antivirus software.
If you’re looking for a robust antivirus solution with a wide range of features, AVG is the clear winner. However, for users with older systems who need a simple, free solution, Microsoft Security Essentials may still serve its purpose, though it is highly recommended to upgrade to a more modern antivirus solution.
In the end, the choice between AVG and Microsoft Security Essentials largely depends on your specific needs, the version of Windows you’re using, and how much you are willing to invest in your security. For most users, AVG offers a more comprehensive and up-to-date protection system that is well worth the cost.
