Sometimes software removal and uninstall is not exactly straightforward, so we hope this article can help you out. Let’s get to it.

What is Avast?

Avast Security detects viruses, ransomware, and other malware on your computer. It can warn you of unsafe websites or scan your Wi-Fi for vulnerabilities. What’s more, you can use Avast Security to run scheduled scans on your Mac, as well as scan removable drives or select individual files that you direct it to check.

You can get both the free and premium version of the antivirus on the official website avast.com.

Avast’s features include the so-called Core Shields. These help protect specific aspects of your system – File Shield scans files added to your Mac, Web Shield blocks web attacks and unsafe downloads, and Email Shield protects from unsafe email attachments. Deploying all these tools will help make sure your system is more protected from outside threats.

Another super handy feature in Avast Security is Virus Chest. This is a place where your files that have been identified as threats are locked. What for? Well, this gives you some time to consider what to do with them. Maybe an infected file is valuable and you need to recover the data. Maybe you can consult with a pro to restore your information while safely avoiding the threat contained in the file.

With these and more features, Avast Security and Avast Premium Security help protect your Mac.

Why would you want to uninstall Avast Mac software

Before we get to figuring out how to uninstall Avast on Mac, let’s look at some of the reasons people uninstall this antivirus.

First off, some people want to start using a different antivirus for their system. Another reason to remove Avast from Mac can be the antivirus using up the laptop’s resources.

To check how much CPU and memory Avast Security is taking up on your machine, you can use iStat Menus. It’s a helpful app that brings your Mac’s stats to the menu bar. You can monitor various indicators of your Mac’s activity in real time.

If you feel Avast is taking up too much resources, you can confirm your hypothesis through iStat Menus.

You might also feel your antivirus is hindering your WiFi speed. But sometimes a connection issue might have nothing to do with the antivirus, and your WiFi might genuinely be pretty bad. Start by testing your internet connection speed with one of the free speed test tools online.

Next, get a detailed overview of your WiFi with a WiFi analyzer app, like WiFi Explorer. This app provides you with insights on your WiFi connection and can help troubleshoot issues.
