You might have heard that Macs are immune to viruses. This isn’t entirely true – there are viruses, though their volume and danger are lower than with other operating systems. But, they still need to be taken seriously.

Since the popularity of Macs has increased over the years, so has the threat of viruses and malware. This means it may become necessary to have antivirus software on your computer.

There are tons of options on the market ranging from more comprehensive to more straightforward. If you’re not quite sure which one you want, we have created this comparison chart here to help make your decision easier.

This security suite is composed of two applications: VirusBarrier X9 and NetBarrier X9.

The first thing the antivirus does is protect your Mac from viruses and malware of all types. It constantly updates the threat database, performs real-time protection, and does automatic deep scans following a scheduled scan, making it a very reliable product.

Avast Security

Best Antivirus for Mac: Best Options in 2021

Avast is probably the best-known free antivirus software for Windows users – they also have a version for Apple computers.

The free version of Avast includes protection against viruses and malware and warnings about unsafe websites. In addition, the threat database is constantly updated.

If you want the extra features that Avast Pro offers, it may be worth paying for them. For example, in-app WiFi alerts don’t always give out intruders in time, but if you have real-time monitoring top of mind, then this tool fits your needs. One of the most beneficial aspects of AI is that it can stop ransomware attacks. That means there’s no chance your files could be altered without your knowledge – especially by encryption.

Avira is a much cheaper option for those who want to protect their Mac but don’t want to invest in software. You can get a free version from the app store if you have OSX.

The Avira free antivirus does not offer some of the features that other antivirus software does. To protect USB drives, you would need to upgrade to their premium version, for example. However, it still includes all essential functions of real-time protection.

Do I really need an antivirus on my Mac?

At the beginning of this article, I mentioned that -despite their prevalence- viruses and other types of malware are also far less widespread on the Mac. We also need to say that infecting your computer with an infection is more complicated since macOS includes built-in protection mechanisms against unauthorized software executions.

Considering this point, and with an eye on effectiveness and simplicity, I would recommend installing anti-virus software for inexperienced users and shared computers. This software should protect both your computer and any other connected external drives. This reduces the risks, and it will be more difficult for the Mac to end up infected.

If you have more advanced knowledge, you usually take steps to avoid installing software from unknown sources and always make backups. That will help lower the risk of ending up infected, although it can never be completely ruled out (here are some tips to know if you are infected and also on how to remove a virus). If you are unsure, then you should install one of the best antivirus programs on this list.
