Best Free Computer Security Software

Best Free Computer Security Software

Are you looking for some of the best computer testing software? You are at the right place. Today we are going to throw light on some of the best free computer testing software downloads. Let’s check them out:


Avira Free Security for Windows is one of my favorite free antivirus computer security programs on the market. One of its best features is that it has one of the most capable anti-malware engines out there and includes more free features than any other competitor available in 2021! It’s also really easy to use, so I can see why this would be such a great option as an automatic backup or secondary protection system.

Avira’s anti-malware engine detected all of the malware files in my testing, and I was able to run CPU-intensive programs during scans with almost zero slowdowns. Paid products like McAfee and Norton are equally effective at detecting malware, but their full disk scans will slow down your system much more than Avira will.


Bitdefender Antivirus Free is the best anti-malware scanner on the market, consistently scoring 100% perfect malware detection and removal rates in all of our tests. Its cloud-based engine silently runs in the background with only essential notifications when suspicious program activity occurs, and scans are done automatically unless you decide to adjust settings!

The Bitdefender security software ran faster than any on the list and had a minimal impact on my computer’s performance. I watched videos, played games, or ran other CPU-intensive programs without interruption throughout the scanning process. If you feel like your computer is under stress, you can also choose the best computer stress testing software and install it.


TotalAV Free Antivirus provides excellent virus and phishing protection. During my tests, TotalAV’s cloud-based malware scanner detected and removed more malware samples than most antivirus programs — successfully identifying even very tricky ransomware, spyware, and crypto-jacking files.

TotalAV’s phishing protection is also very good. It uses a huge blacklist to identify known phishing sites and an AI-powered phish detection system that identifies new threats in real-time. The anti-phishing tool scored a near-perfect detection rate in my testing and stopped me from entering more malicious websites than Chrome’s native browser extension ever could!


Panda Free Antivirus for Windows is the perfect solution to protect your computer from malware, adware, spyware, and ransomware. In my tests, I found that Panda’s antivirus scanner detected more files than Windows Defender as well as blocked most of the file downloads with real-time protection during testing.

Panda’s antivirus includes a VPN for your security and peace of mind. Its fast connection speeds will keep you connected to what matters most, with data limits that are on par or better than other providers! You can also access one server at the same time, which is perfect if unblocking geo-restricted content like Netflix USA is your goal.
