Opera is a popular web browser with an abundance of features. Although this browser isn’t as popular as Chrome or Firefox, it still has a dedicated user base.

If you’re using Opera and you’re looking for antivirus software, today we’re going to show you the best antivirus tools that work with it.

All antiviruses are fully compatible with all web browsers, and the only difference is that some apps come with a dedicated browser extension to scan the websites you visit.

Even though some applications on our list don’t have a dedicated extension for Opera, they offer great security and reliability, so you should try them out regardless.


Does Opera GX have virus protection?

No, Opera GX doesn’t have its own antivirus. Instead, Opera GX provides some amazing features to protect your privacy. It comes with a free VPN that you can use indefinitely.

Also, it comes with a built-in ad blocker so no spam ads or fake notifications can harm your PC. Moreover, it has a tracker blocker to keep all trackers away from you.

It’s important to remember that using your browser’s antivirus alone is not enough to protect against phishing, ransomware, and more. We highly recommend using a third-party antivirus for all tasks you do online to virtually eliminate the chance of infection.
