Our results in this section of the review will be based on Windows 10, since that is the current version of the Windows operating system. Avast also has versions available for Mac, Android, and iOS, and we will talk about them later.

Antivirus Protection

Antivirus protection almost always works the same way between different companies. They all do an initial scan, and they match the results with their database. All of the Avast versions offer good features. Once Avast has scanned and secured your personal computer, it will continuously update the program. If you get new malware, you can upload it to Avast for more research. It will also scan emails, attachments, and rogue webpages. You can schedule it to perform the scan of your local files as often as you wish. Be aware that Avast will not scan online directories of files.

Avast will look for questionable browser extensions. Weak passwords, outdated software, drivers, compatibility issues, and performance problems are monitored by the software. However, to fix any performance problems, be ready for the up sell for their cleanup tool. Avast will scan any drive you want by right clicking on it, including thumb drives and external storage. It will not automatically scan USB devices when they are first plugged in.

Installation and Support

Getting started with Avast is easy. After you have downloaded the software, go ahead and install it. Once everything is done, right click on the Avast icon in the menu bar (it should look like the letter A in an orange circle) and select Open Avast user interface. You will see the message below showing that you are protected.

Next, go ahead and click on the button that says Run Smart Scan to start the process of scanning for threats. As you see, the scan will start and perform the tests.

Depending on how many files you have on your computer, scanning may take awhile. As for getting help with questions or setup, Avast offers in-product support. You may also email them and they will get back to you within 24 hours.

Antivirus Performance and System Impact

Two of the factors to look at with any antivirus software are performance and impact. As far as the tests go, the free version of Avast is quite slow. However, Avast Pro Antivirus has better performance numbers. There seems to be very little impact with an active scan, when compared to others in the industry. Another thing you want to look at is the number of false positives reported. Several different independent labs have verified that Avast has very few false positives. In a real world test, Avast shows only a .3% compromised rate. As far as on demand scanning goes, we found it to be good. It was stated that Avast Pro Antivirus may cause some applications to open more slowly because it scans them, but we have not noticed any speed decrease.

Our Tests

Have you ever wondered if your antivirus software works? Several companies offer tests to make sure yours does the job. Some of them are load tests, while others will verify that the software is detecting viruses. Eicar.org has several tests you can use to ensure your antivirus software is working. When we ran the virus tests while using Avast, we got good results. As you see in the image, Avast blocked the threat.

We also created a fake virus string in a text file and saved it to the computer to test the antivirus. As we expected, Avast did not detect the virus immediately. However, as soon as we did the active scan, the antivirus software found it. Avast would not tell us what file it found, but the software removed it immediately. We would have liked to see information on the file.


If you want to bring up the interface to do an active scan, right click on the Avast icon in the task bar. It will be an orange circle with a stylized lower case “A” inside. Click on the top option. It should say Open Avast user interface. In the image below, you will see the console showing the results of the last scan. If you have issues, click on the resolve all button.

That will take you to the screen you see below. Now, click on skip. When we clicked on resolve all, nothing happened. We later found that Avast had already deleted the file.

The second screen you see is the one below. It will tell you if you have any network problems and what they are.

The final screen gives you the option to clean up the performance issues. That is the tool we mentioned earlier that you can purchase. The interface is pretty easy to use, but we would like it to be a bit more interactive.

Avast Mobile Security for Android

The version for Android is called Avast Mobile Security. If you want an integrated solution, this is the one for you. Let’s start by showing you how to download and install it. Go to the Google Play Store and type in Avast Mobile Security. When you locate it, click on the button that says Install. Next, click on Open.

Now that it is installed, go ahead and click on Continue. In the next screen, you can scan the device for threats as part of the Smart Scan. By clicking the boost button, you can stop any running tasks to increase device performance. Other buttons include a wifi scanner, app stopper, and an app locker.

As you would anticipate, the features will help keep you safe. There are also several other apps you may install from inside of Avast Mobile Security. When you click on Scan this device under the smart scan heading, you can see if your device is safe. If it isn’t, you will be prompted to fix it.

Final Thoughts

Overall, we found Avast Pro Antivirus to work well in our testing. We loved the fact that it found the file we created quickly and eliminated it. It would have been nice to see the file Avast deleted, but all records of it disappeared. The interface is very easy to use and will take care of problems. We also like that Avast offers so many options with their different plans. We recommend Avast because of it’s easy to use interface and its great level of protection. Avast Pro Antivirus is one you will want to check out.
