Avast Antivirus Review & Rating


Avast Pro Antivirus has received strong scores from independent labs and contains a variety of useful bonus features that can help provide additional security for your device. However, the paid-only bonus features available for Avast Pro Antivirus may not justify the expense when compared to other options.

✓ Minimal computer impact
✓ Fairly fast antivirus scans
✓ Solid scores from independent testers


Avast Pro Antivirus has the same strong antivirus protection that Avast Free Antivirus offers, with a few additional bells and whistles that provide strong additional protection, like the Real Site component. Real Site makes sure that your system is connecting to a reliable DNS (Domain Name System) server; this helps prevent hackers from redirecting your browser to a fake website that’s showing the domain you’re expecting. For example, Real Site can defend against someone redirecting you to a fake bank site and stealing your information.

Avast Pro Antivirus also adds a Sandbox feature to their lineup, allowing you to run programs you want to use but aren’t sure are safe.


Many of the features available for Avast Pro Antivirus can also be found with the Avast Free Antivirus option, and Avast Pro Antivirus teases you with links to even more advanced options that you can only unlock through further upgrades. While the Real Site protection and Sandbox are useful, they may not justify the cost over the free version that’s available.

# “Avast is easy to use, has a variety of useful - and occasionally uncommon - protections.”

Avast Pro Antivirus receives solid scores from independent testing labs, with very strong antiphishing protection and the same suite of additional security features that Avast Free Antivirus provides. It’s easy to use, has a variety of useful - and occasionally uncommon - protections (like the WiFi Inspector, which can check your network for security issues and help you resolve them), and doesn’t take up a ton of system memory to use.

If you’re someone who may work with potentially dangerous programs or you want the extra defense against DNS attacks, Avast Pro Antivirus is a decent investment. However, Avast Free Antivirus offers many of the same benefits at no cost to you.

User Experience

Avast Pro Antivirus upgraded their user interface to be clean and easy to understand. When you first launch the program, you’ll be taken to the status screen, which lets you run a “smart” scan (a shortened version of an antivirus scan) to make sure your essential files and programs are protected. Avast Pro Antivirus has 4 buttons along the left side - Status, Protection, Privacy, and Performance. Clicking on any of these opens up a new tab which shows you the options available to you.

The only place this can be confusing is the Performance tab, which allows you to click on “Cleanup” to scan your computer. However, once the scan is done, if you want to take action, you need to pay for their Cleanup feature. Overall, Avast Pro Antivirus’ user interface is simple to understand and can be used by anyone with any level of computer experience.


Customer Support

One of the great features of Avast Pro Antivirus is the ability to send a support message from directly within the user interface. Clicking on the “?” in the upper right brings up the help menu, with answers to general questions; if you cannot find what you’re looking for, clicking “send a support request” at the bottom of the help screen gives you a direct message to technical support.

For premium users, there is also a direct phone line and 24/7 support for any potential antivirus issues you run into. You simply have to log into your account on the Avast website. There’s also a support forum and an intuitively organized support center, if you want to search for your answer on your own.

“Never had a problem”

by Sophia on 06/08/2017

"I am a big fan of Avast Pro Antivirus simply because it is very user-friendly and very easy to install. There is step by step guides and once you install it, Avast runs quietly in the background. You get a Wi-Fi scanner that scans your connection for security problems and you also get an awesome software update tool that looks for things like security patches and alerts you when they're found. All you have to do is click 'update' and Avast goes to work. Avast will scan links while you're browsing the internet to determine if they're safe or not to click on. I trust this product and run it on my own computers and have never had a problem nor have I ever had any computer issues while running this software. I recommend this product to family and friends and will definitely purchase it again."


“A user friendly product!!”

by Greg M. on April 2015

"While most antivirus software packages tend to be either overly aggressive or have more holes than swiss cheese, Avast has struck the sweet spot: a very high detection rate but with very few false positives. Avast has developed a number of "shields" to add additional protection on top of the usual file system shield, such as network, browser, P2P, email, script, etc. It also has some great features like sandboxing (if it detects an app that it thinks might be suspicious, it sandboxes the app when running it), a silent/gaming mode, and easy access to controls that disable the shields for a set period of time (allowing you to quickly get Avast out of the way if it's being overly intrusive without permanently disabling it). You can't beat the price - free - for personal use; central management console with remote deployment capabilities available for businesses, but a cost similar to the industry behemoths."
