A popular free antivirus software, Comodo has been around for almost a decade. While it does have its share of critics, its users love its ease of use and ability to protect their computers from viruses.

Some of its main downsides are its buggy features and outdated design. Still, if you’re looking for an effective Windows 8.1 antivirus, consider Comodo.

This free antivirus software is jam-packed with useful features. It has a unique Default Deny Approach to prevent unauthorized access to crucial parts of your computer.

It uses technologies like Containment, HIPS, and Viruscope to protect your PC against all types of malware and zero-day attacks.

There are several other features you can use to further protect your computer. For example, you can use the Secure Shopping feature to isolate your browser from malware while shopping online.

In addition to blocking malicious programs, Comodo also offers a game mode that allows users to ignore antivirus alerts and play games without worrying about catching a virus.

Comodo’s “secure web browser” is based on the open-source underpinnings of Google Chrome, which has been shown to be effective in protecting computers from malicious files.

It is lightweight and offers constant virus scanning and behaviour analysis reports.

It’s important to remember that most malware attacks are unknown threats, that the security community has not yet tackled.

You may be wondering if Norton’s antivirus software for Windows 8.1 is compatible with this new version of Windows.

There are many reasons why you might want to upgrade, including performance and security improvements.

Norton 360 provides everything you would expect from a full-featured antivirus solution – scans, disinfects, and backs up your files.

If you’re looking for something simple and straightforward, this may just be what you want to use.

For one thing, Windows 8.1 isn’t as stable as previous versions of Norton, which made it an excellent choice for users of that operating system.

Regardless of your level of computer knowledge, Norton AntiVirus can help protect you from malicious software threats.

Its real-time protection will help you stay one step ahead of potential threats. It also defragments your hard drive and improves boot time.

If you’re in the market for antivirus software for Windows 8.1, AVG might be the best choice. This free antivirus program installs quickly and features a paid subscription option as well.

AVG internet security has become a major player in the world of antivirus software. With their wide selection of features that are easy to use, they have been able to rise up above the rest.

This program gives you access to a plethora of features, while not being overly complicated.

They offer protection against malware, spyware, adware, phishing, spam, and other forms of online threats that can cause harm to your computer.

Its dashboard is very user-friendly, with icons for each function. You can see which programs have more features and whether they’re worth paying for. Once you pay for the subscription, the dashboard turns green.

AVG’s built-in security features aren’t perfect, and it’s important to use an antivirus program to protect your computer. AV-Comparatives’ tests showed that Microsoft’s free protection didn’t protect users as well as AVG. AVG blocked 100 per cent of malware threats, whereas Microsoft’s solution only protected 94.7% of them.

This is a clear win for AVG, as Microsoft has stopped providing support for Windows 8 since January 12th, 2016.

Furthermore, Microsoft announced the end of extended support for Windows 8.1 in January 2023, and therefore strongly recommends that Windows 8.1 users upgrade to the latest version.

Apart from protection, you should also choose antivirus software that can clean and repair damaged files. AVG’s SONAR technology guarantees powerful protection against malicious files.

AVG is also known for its proactive security features. Its CyberCapture cloud-based scanner sends suspicious files to the cloud for analysis, and it can also prevent future attacks from taking place on the machine.

You should upgrade to the full Internet Security or Premium Protection plan if you want maximum protection.
