Why McAfee Slows Down My Computer

Why McAfee Slows Down My Computer

McAfee is a great antivirus solution when it comes to protecting your computer from viruses, Trojans, worms, data or identity theft programs. However, you may experience a slowdown issue when surfing the internet, checking emails, or navigating from one program to another. Slowdown can occur due to multiple reasons explained below in the McAfee antivirus support guide. The guide will also help you fix some of the common McAfee antivirus issues that slow down your PC.


If you have Low computer memory (RAM), you may experience a slowdown in your computer when McAfee antivirus installs updates, patches etc. Often, such problem occurs in an old computer that has low RAM. To get rid of the slowdown problem, add a new RAM stick to your computer. In other words, upgrade its hardware.

If your internet connection is slow, it may take more than ever for McAfee to run a virus scan, download and install latest updates, or do real-time scanning. So, if you are doing something on your computer like browsing the internet or checking emails while McAfee is running in the background, you may face a slowdown problem. Contact your ISP and ask for a high-speed broadband connection. Besides, let McAfee run virus scans or updates when the computer is idle. Yes, if the computer is sitting idle, launch McAfee and have it update or run a virus scan.

If you have another antivirus program on your computer along with McAfee, it can cause your computer to slow down terribly. It is because two antivirus programs always conflict with each other as they try to fetch files simultaneously for your computer. You must always uninstall the other antivirus program to make sure that McAfee runs peacefully and properly on your computer.

If you have a built-in firewall in your McAfee antivirus program (a newer McAfee version comes with built-in firewall), it may cause issue with your internet connection. If you have another firewall program installed on your computer, disable the McAfee firewall. It will help improve your internet connection speed, making your browsing faster.

Sometimes a poorly-written McAfee update can also be responsible for decelerating your computer’s speed. If you have narrowed down to check that it’s not a program or your computer which is causing the slowdown, uninstall the McAfee update. If you don’t know how uninstall a McAfee update, restore your computer to an earlier time. It may undo any recent changes like a software install you made to your computer. You always have the option to reinstall the software.

Additional Tips:

Your web browser also makes a difference to the browsing speed. For example, Mozilla Firefox and Chrome are faster web browsers than the Internet Explorer. In case the problem persists, contact a McAfee antivirus support service.
