Why Is Avast Antivirus Slowing Down The Computer

Avast slowing down the computer is a common problem that users encounter. But that does not mean that the antivirus is not valid. It is a free antivirus that has long been protecting our computers from a variety of threats. So, don’t always blame the antivirus for poor performance because there may be some issues with your system causing the problem. Let’s find out the reasons behind Avast slowing down your computer;

1: Your System Lacks Storage Space

Avast Antivirus keeps on performing many security checks on your machine, and you may not even know about it. Starting from virus scanning and background scanning to computer cleanup-everything is Avast’s responsibility. So if you are facing the ‘Avast  high CPU usage’ issue, it’s probably because your system does not have enough space. If your CPU does not have enough RAM, your system will become slow every time Avast performs these real-time security checks.

How Will You Fix It?

There are several ways to fix the high CPU usage problem. For starters, you can simply upgrade your RAM. But there are other solutions too. So, let’s take a look at them:

  1. You can remove the Avast Antivirus from your machine. To do that, open the icon, tap on the components option, scroll down, and press the uninstall option. Restart your PC once after uninstalling the program.
  2. You can also update the antivirus. For that, you need to open the app, go to the update menu, and update both the program and virus definition options. When you are done, check if your CPU usage is normal or not.

2: Your System Lacks Disk Space

If your hard disk is full, your system will automatically start performing slower. On top of that, if your Avast setup is already running, it will keep on making your hard disk full. In addition, you’ll see in the taskbar that instup.exe is always running and updating, so when you try to close it also, you will be prompted. In this context, it is better to just uninstall Avast from the control panel.

Even if you manage to uninstall Avast, your system still may run slow. So, you have to free up some disk space to ensure it goes back to its optimal performance level again. Find out how to do that here:

  1. You can uninstall the apps that you no longer need or use. Just find the programs menu in the settings option. You’ll find the long list of apps here. Uninstall the ones that you don’t use anymore to free up some disk space.
  2. There may be some large files that are taking too much of your CPU space. So, head back to settings again, and check the properties option of each of those apps. The ones you find are the largest; start deleting them.

3: Too Many Avast Features Are On

It is indeed that Avast Antivirus is useful software with a wide array of features. But we don’t always use all the features, right? But, when Avast keeps on running in the background, it uses all those features automatically. This is a significant reason why Avast is slowing down your computer. To get rid of this problem, you have to turn off a few of its features. So, let’s see how to do that.

How Will You Fix It?

Before we tell you how to turn off the Avast features, let us tell you what you will do when you see Avast UI failed to load. Just update the antivirus, or uninstall it before you proceed with the other steps.

5: There Are Many Startup Programs

People often ignore when too many startup programs run on their computers. As a result, it slows down your computer, and when you run Avast Antivirus, it makes the machine even slower. With so much software open on the system, your PC is bound to run slow, so let’s see how we can resolve that.
