Best Free Antivirus Software for Windows in 2023

Every computer on this planet can face a virus attack at any time. Therefore, it is better to have antivirus software installed on your computer. Good and powerful antivirus software will cost you some money. Fortunately, there are 10 very reliable and best antivirus programs available outside the Internet.

Selecting the best antivirus software depends on two main factors: the region where you live and the operating system such as Windows 10 or Mac.

Let me explain this a little more. That would allow you to select the best free antivirus software for your PC.

How to Choose the Best Antivirus Software

Now let’s get this clear. It’s a sheer myth to believe that Apple or Mac computers as we know them are immune to virus attacks. No, they’re not. Since there’re fewer Apple computers, the number of virus attacks is relatively lower.

About 77 percent of computers use the Windows operating system. Hence, they are common targets for virus attacks.

You will also have to select antivirus software according to your region. That’s because all antivirus programs need updates. When an antivirus company detects a threat in your area, it will release an update or patch to protect your computer.

That doesn’t mean you should download an update merely because hackers aren’t targeting your region. Computer viruses can strike anywhere. Hence, it would help if you had that update too.
