I wrote about Windows Defender in 2017, suggesting that you didn’t need to pay for anti-virus software because the one bundled with Windows 10 does a good job and integrates perfectly with the OS. Since then Windows Defender has been improved* and does a really good job of keeping you safe online; so there’s really no need look for an alternative, and especially no need to pay good money for protection.
I know many of you remain unconvinced about free anti-virus software, and so even this post won’t convince you. But for the rest of you, please trust me when I tell you that free software really does do the business!
However, you might say that you really don’t trust Microsoft (despite the fact that you trust them with Windows 10 on your computer in the first place), in that case here’s a great free alternative.
I haven’t used Avira, but I have it on good authority that it’s the best free alternative to Windows Defender. It blocks all kinds of threats (including spyware, adware and the like), offers real-time protection and updates, and can repair infected files. It doesn’t hog system resources (unlike some paid-for products) and is speedy and efficient. There are even free add-ons that can boost your protection.
So my advice, for what it’s worth, is to stick with the free Windows Defender that comes bundled with Windows 10, and certainly don’t pay good money for what can actually be inferior. But if you must have something else, you can’t go far wrong with Avira!
* I think Windows Defender is called Windows Security now. That’s the label on the settings window and taskbar icon anyway. It was the anti-virus software recommended by WebUser magazine in 2019.
