Manjaro Linux, like other Linux distributions, has a lower risk of encountering viruses and malware compared to Windows due to its open-source nature and smaller market share. However, it's not entirely immune to security threats. Here's how Manjaro Linux deals with viruses and malware:
Built-in Security Features: Manjaro, based on Arch Linux, comes with a variety of built-in security features. For instance, it uses the Pacman package manager, which is designed to only install packages from official repositories, reducing the risk of installing malicious software.
Regular Updates: Manjaro provides frequent updates to its system and software packages, ensuring that security vulnerabilities are patched promptly.
Antivirus Software: While Linux is less susceptible to viruses, users can still install antivirus software for added security. ClamAV is a popular open-source antivirus that can be installed on Manjaro to scan for and remove malware.
Firewall: Manjaro typically comes with a firewall enabled by default, such as UFW (Uncomplicated Firewall), which helps to control incoming and outgoing network traffic based on predetermined security rules.
User Privileges: Linux systems, including Manjaro, encourage the use of user accounts with limited privileges. This means that even if malware is executed, it often cannot make significant changes to the system without the user's explicit permission.
Community Support: The Manjaro community is active and responsive, providing support and updates to address any security issues that arise.
Example: If a user suspects their Manjaro system is infected with malware, they can use ClamAV to scan the system. The user would open a terminal and run a command like sudo clamscan -r /home/user/Documents to scan a specific directory recursively for malware. If threats are found, ClamAV can remove or quarantine them.
For additional security measures, especially in a cloud environment, users might consider services like Tencent Cloud's Anti-DDoS and Web Application Firewall services, which offer protection against various types of cyberattacks, though these are more focused on network and application-level security rather than traditional antivirus protection.
