What is Avast Firewall and how does it work?
Avast Firewall is a security feature offered by Avast Antivirus, a leading cybersecurity software. It is designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. The firewall acts as a barrier between the internet and your computer, blocking unauthorized access and malicious activities.
Avast Firewall uses a combination of signature-based detection, behavioral analysis, and reputation-based scanning to identify and block potential threats. It can detect and block malware, ransomware, Trojans, and other types of malicious code. Additionally, it can also detect and block suspicious network activities, such as unauthorized access to your computer or data transmission.
Is Avast Firewall free?
Avast Firewall comes as a part of Avast Antivirus software, which offers both free and paid versions. The free version of Avast Antivirus includes the basic features of the firewall, such as network traffic monitoring and blocking of malicious activities. However, some advanced features like advanced network scanning and customizable rules are only available in the paid version.
It’s worth noting that while the free version provides a good level of protection, it may not offer the same level of customization and advanced features as the paid version. If you’re a home user, the free version might be sufficient, but if you’re a business user or need advanced protection, you may want to consider upgrading to the paid version.
