Windows Defender VS Avast

Windows Defender vs Avast: which is better for you in the term of security-related features? Next, there are some comparisons between Windows Defender and Avast from five aspects.

Windows Defender Firewall is the best feature in Windows Defender that protects your computer from malicious traffic. It pays close attention to all incoming and outgoing network connections and rejects unauthorized access.

Like most anti-virus software, the software has a signature-based scanner that periodically checks for various digital threats. Due to Microsoft’s cloud-based malware database, the definition (or signature) of the software is regularly updated to provide instant protection against new and emerging threats.

In addition, there’s also the “Find My Device” feature, which lets you track your computer if it’s lost or stolen. This feature is very useful for your laptop. If you think that sensitive data is at risk of being stolen, you can also delete the data or lock the computer.

Windows Defender also includes a set of parental controls. It can be used to monitor your child’s online activity, use an automatic timer to limit screen time, and prevent children from accessing certain websites or apps that are not suitable for their age.

Now, let’s see the feature of Avast. Avast offers different products for Windows and macOS. Here, I will introduce the products for Windows only.

1. Avast Free Antivirus – the first product offered by the company. The program protects against different types of digital threats, but you won’t find any advanced security enhancements or utilities in the program.

2. Avast Internet Security – the company’s first premium offering. This program provides comprehensive anti-malware protection and an excellent firewall that protects you from various threats and spam filters. This will keep your inbox clean and help you avoid annoying spam and phishing emails

3. The package of Avast Premier includes everything that is jammed into the Internet Security Suite, as well as a file shredding tool, which allows you to permanently delete any sensitive files that you don’t want to be hacked. This software also prevents from spying on you through your webcam.

4. Avast Ultimate – the company’s all-inclusive quality products. This includes everything in the previous suit, and you can use the password manager to store all of your passwords in the digital vault. This is a VPN utility that gives you anonymous access to restricted content in your geographic area.
