Best Free Antivirus Software For 2025

Choosing the right antivirus can be challenging, especially with so many claiming to be the best. TotalAV stands out for its affordable plans and range of features, but can it truly protect your digital security?

I tested TotalAV to see how it stacks up. I evaluated everything it offers — from basic antivirus scanning to advanced features like a VPN, ad blocker, and system optimization tools. I also checked its usability, customer support, and pricing to determine whether it provides real value.

I’ve tested dozens of security tools over the years, and most browser security extensions make big claims but fail when it really matters. Guardio stood out because it’s built to protect your browser and mobile device from scams and malware before they can even reach you. That’s a different approach from traditional antivirus software.

But does it actually provide real protection, or is it just another unnecessary add-on? I tested it against dangerous downloads and shady extensions to see if it can truly keep you safe.

After extensive testing, I can confirm that it does a great job at securing your browser and mobile from online threats. However, I wouldn’t rely on it alone for full desktop protection.
