Is Free Antivirus Software Good Enough?

Choosing a program that will keep your computer safe from viruses and other cyberattacks is no easy feat. How can you choose the best software for your computer if they all look the same at first glance?

Sure, lots of reviews on antivirus programs are now available online. Comparing all of them and making sure that actual customers wrote them is another story though. Remember the time you bought that cheap blender because it had lots of 5-star reviews? Then it turned out to be a complete waste of money? The same thing can happen to you if you don’t take the process as seriously as you did with any other product you’ve bought.

As you start your search for the best antivirus software, you will come across two kinds - free and paid antivirus.

Paid antivirus programs offer a complete suite of security features. The bad news is you’ll have to commit to making recurring payments for them. The good news? Most companies now offer free versions of their antivirus software. These programs can give you protection from viruses and other malicious software.

Here’s a list of what you’ll get from free versions of most antivirus programs out there:

These are just some of the features that are usually included in free antivirus software. The following features are usually available in paid versions only:

It's also important to note that free users usually get limited access to customer support. However, most antivirus companies have an extensive knowledge base where you can get answers to your questions in an instant.

The Bottom Line

If you’re the type of person who doesn’t like paying hefty monthly or annual fees until you’re completely sure about your purchase, a free antivirus program will do you a world of good. After all, you can always upgrade to a paid plan once you’ve found a program that ticks all the right boxes. You can also uninstall it and replace it with another software if you are not happy with its performance.

All the choices out there can be quite overwhelming. My advice? Download free antivirus software from a reputable company to get started. No commitments, no fees - just plain excellent protection against widespread malicious software.
