In this article, we have listed the best free antivirus of 2017 for your Windows PC. In the link below, we explain the advantages of free and paid antivirus.įree antivirus are undoubtedly the most popular. The first choice is evident: free or paid antivirus?

It is a basic protection that works when using the PC casually, but once you start downloading content, visiting forums and social networks, and browsing all kinds of webpages, it is recommended to install a good third-party antivirus. This is something that some technology companies already offer, such as Samsung in its latest Galaxy phones. With the Windows 10 Creators Update, the brand has improved the security, putting it in the new Windows Defender Security Center where you can manage the antivirus, the firewall, the SmartScreen filter against phishing, and the parental control.Īdditionally, the latest Windows 10 Fall Creators Update introduces a tool against ransomware so you do not lose all your files if it attacks you: a secure folder that only you can access.
