Best Free Antivirus for PC In 2022
There’s no denying that the internet can sometimes be a dangerous place for PC users, especially Windows users. No operating system, including Linux, is antivirus/malware; if you’re a Windows user, your chances of getting infected are higher. To protect your computer from malware, there are many antivirus software available. In this article, let’s go through some of the best free antivirus software options to help you choose the best.
“But does antivirus really work?” Well, the answer is yes and no. If you’re using Windows 10, Windows Defender is more than enough. If you’re on an older Windows version, many free scanners (like Bitdefender, Kaspersky, Avast, etc.) do a decent job at the best free virus protection. Needless to say, their paid counterparts offer some advanced features and dedicated support. That’s why I’ve also added links to some noteworthy advanced options. Be sure to review and keep your device safe from threats in 2021.
What to look for when choosing the best antivirus software

Although Windows Defender was introduced back in Windows XP, it didn’t do much to protect users beyond scanning files and reporting malicious ones, and some even said this feature was broken. Before Windows 10, Windows Defender was little more than an application that took up space on your computer.
