Did you encounter an issue with McAfee making the computer slow down? For years, McAfee has been known as a well-renowned brand that has been continuously serving virus protection services to its customers.

Your McAfee system can help you keep your computer, including other devices, free of threats.

These threats involve any type of online threat that has any chance of redirecting your data to a third party. Not only protecting your data from the unknown party but also keeping your privacy on top priority is McAfee’s motive. With McAfee, you can easily block unwanted sites or content that can harm your device. With the availability of hundreds of features and all of them running on your system for protection can simply slow it down. There can be other reasons too. We will discuss them in this guide to resolve the issue of McAfee making the computer slow down.



Even though the McAfee system can help you wash out the external threats, the side effect of its constant intrusion and processor hogging symbolizes that your computer will run much slower than expected. However, to strike a healthy balance between a suitable level of system resources and threat protection, you need a change of formulas. You might think it will be gone once you try your tricks, but trust me, the error controversy is just beginning.

Usually, the issue occurs when you have installed the McAfee antivirus to run different programs to detect system threats. These issues can easily make you frustrated and irritated at the same time. If you are struggling with this problematic situation and want to know how to fix it, you are at the perfect spot. Let’s find out the methods that can help to resolve the issue of McAfee making the computer slow while performing other tasks.


As the ruler of millions of users, McAfee is designed to safeguard your PC or other devices from malware attacks or viruses. But providing complete protection can create a negative impact on your PC performance. The issue of McAfee making your computer slow is nothing new to the tech world, and there are a plethora of reasons behind this mystery glitch. Before we proceed to fix McAfee making the computer slow, here are the reasons that can cause an issue with your PC performance.

After installing McAfee, you need to look for these factors when your PC starts to slow down during other tasks:

  1. If your PC has restored excess junk files, it can impact PC performance.
  2. When your system has failed to balance disk space.
  3. The error is possible if you are using an outdated McAfee antivirus version on your device. 
  4. Check McAfee if you have enabled auto-scan features.
  5. If you are using an outdated operating system on your device.
  6. When you use the system continuously without rebooting.

These are some of the usual reasons behind the issue. But regardless of the problem that occurred, you can apply the solutions given below.


Installing an antivirus is the most important application you can acquire on your laptop, PC, or desktop. Nowadays, you can’t operate on online platforms without securing your data and privacy. So, what can be a better alternative than McAfee activation for any of your devices? Of course, there will be a point when you encounter glitches like McAfee making the computer slow. But there is always a solution for tech errors after McAfee download.

The best part is you can resolve them on your own. It means you don’t need to spend thousands of bucks on repairing your software. Here we have brought guidelines that involve different fixing methods. You will need to apply them accordingly and check what works for your system. Also, you should note that skipping between the suggested steps might lead you to another McAfee software glitch. Let’s get started with the methods.


Auto-scan is the feature that is offered with the software to ease the threat scanning schedule. After attempting McAfee login, you can enable this feature for an automatic schedule scan. It is a feature that scans the PC to dispose of potential threats (online or external) and malware in the backend while you are performing other tasks. It puts a load on the system memory, and eventually, the PC performance gets steady. So, sometimes turning off the “Auto-scan” feature helps to retrieve PC performance after McAfee download. To resolve the issue of McAfee making the computer slow, you need to attempt the instructions to disable the auto-scan feature.

Here is how you can perform the steps and retrieve the speed of your PC/ laptop while working on your system:

  1. First, you will need to turn on your PC.
  2. Then, launch the McAfee security antivirus.
  3. Next, you have to go to the Settings section from your dashboard.
  4. After that, select the Auto-check option.
  5. Now, turn off the auto-scan settings.
  6. Thereafter, you need to save the settings.
  7. And restart your PC in the end.


Another way to fix the issue of McAfee making the computer slow down during other tasks is to limit the antivirus from accessing system resources. After the McAfee Download, the software might use the system resources, which can lead to poor PC performance. The best technique to avoid this problematic situation is to perform the following instructions:

  1. Start with opening the Run command box.
  2. Enter the Windows + R key from your keyboard to open the Run command.
  3. Next, you need to enter the command “msconfig.”
  4. Now, press the Enter button.
  5. After that, you have to navigate to the Startup tab.
  6. Lastly, you are required to uncheck the boxes that are related to the McAfee manufacturer.


In order to attempt troubleshooting easily, you can try the following steps. When nothing helps fix the issue of McAfee making your computer slow, you can try an alternative solution of reinstalling the McAfee Antivirus. Let’s see how you can do that within minutes.

  1. Get on your PC and uninstall the existing McAfee software.
  2. Then, you will need to navigate to the official website.
  3. Next, perform the steps for McAfee Download.
  4. After that, attempt McAfee login and update the application.
  5. And upgrade the RAM.
  6. Now, you can close the background applications on your system. 
  7. Complete the process after uninstalling heavy programs from your device.
  8. Now, you know how to reinstall McAfee Antivirus and fix the problem.

With the alternative of fixing the issue by reinstalling McAfee on your device, most of the problems will be gone within a second. So, when nothing works, try this one out.


These were some of the ways you can apply when you encounter the issue of McAfee making your computer slow. Now, you must understand that these software glitches do not summarize their disadvantages. These are the common problems you will encounter in every possible software or technology. Sometimes, these glitches are the consequences of using multiple apps or tasks at a time. So, the problem actually resides in how you are operating the system. So, try these methods and get rid of the situation without spending a fortune or contacting external help like expensive technicians.
