How to Fix McAfee PC Performance Error?

by Maria William Software Developer

McAfee is world-renowned manufacturer of security solutions. It offers a wide range of antivirus tailor-made to the specific requirements of consumers and businesses. You can purchase a McAfee antivirus depending upon the particular security needs of your device. For example- businesses require a higher degree of online security to maintain the confidentiality of their data, software and applications. On the other hand, consumers or home PC users can manage with the basic security plan.

Besides providing the users advance level protection, secure online transactions, safe browsing and other features, it may cause several issues. One of the most common issues among those is when the installed McAfee causes slow performance of your PC. This slow performance results in slow loading of your applications and other issues.


There could be different reasons for this issue to occur. Some of these issues include automatic scans, automatic updates, full system scans, inadequate hardware and more.

  • Automatic Scan

McAfee keeps on scanning your computer system automatically, which protects your files, software and applications from all kinds of viruses. This obviously occupies some RAM all the time.

  • Automatic Update

To keep its database of virus definitions up-to-date, McAfee automatically updates itself from its server. This also occupies RAM and some space in from the ROM.

  • Full System Scan

Full system scans keeps your processor busy for some period. This affects on the performance of your PC.

  • Inadequate Hardware

If your hardware doesn’t meet what require by McAfee for a successful running then it may affect the performance of your computer system.


To resolve this issue, you need to follow these steps:

  1. Open up your McAfee Activate program and alter the options so that the McAfee is no longer offer constant protection. Don’t go for constant surveillance! Instead of this, enable the full version of McAfee only when you are moving or browsing to untrusted websites. For the trusted websites you know (Amazon, Flipkart, etc.), you can disable the software.
  2. Stop the security software from eating system resources as soon as your turn on the computer system. For this, open Start menu and then type “msconfig” in the search bar. Once it shows in the result, run the “msconfig” program and move to the Startup tab. Uncheck all the check boxes that are related with this security software. You can find such software by figuring out the McAfee manufacturer name, which is listed with them.
  3. Stop McAfee auto scanning; instead you can do manual scanning by running the antivirus at the end of every day. This simply means the McAfee will not keep on running in the background without caring for what you are doing on your computer system.
