How to troubleshoot device slow issue due to McAfee?

Your device gets into speed issues after installing McAfee due to some reasons.

Common reasons behind McAfee slowing down the system

1. Your McAfee setup is incompatible with the system
2. Low hard-disk or RAM on the device
3. You have another security program
4. McAfee is interrupting with a third-party program
5. You have enabled real-time scanning

Troubleshooting McAfee slowing down the system error

Check the McAfee compatibility

When the question is does McAfee slow down computer; the answer is sometimes. Your McAfee or any security program can slow down the device when it can’t work properly. After installing McAfee, if the device is running slowly then check the compatibility. Go to your McAfee and check the requirements for the hard-disk driver, RAM, and processor. If the setup is incompatible then it won’t run on your device. Whenever you try to run the McAfee program, the device will start running sluggishly.

Increase free hard-disk space 

When the free hard disk space is low, your McAfee can’t scan the device easily. It requires some amount of free hard disk and RAM to work. For RAM, run a fewer number of programs so your McAfee program can get enough RAM cycles to operate. But when the free hard-disk space is less then you have to remove some files or programs. You can also increase the space by adding the SSID or transferring the data to another device or external hard drive. For removing the data, go to the computer and check all the files. Inspect all your installed programs and then remove the apps which you don’t require. When you remove the programs and files, you will get good space on the device. Now run your McAfee antivirus at a good speed.

Remove another antivirus from the device

Speed issues appear on the computer when two programs are conflicting. The user faces this error when he is using another security program with McAfee. Go to the device and then for all your installed applications. If you are using another antivirus or you have an expired antivirus setup; remove it. Expired programs can also interrupt the McAfee scanning program. Once you remove the conflicting program, run the McAfee program reliably.

Disable McAfee real-time scanning feature

McAfee antivirus provides a real-time scanning service. In this service, your antivirus scans all your files in real-time. When you open any file or program; McAfee antivirus will start scanning it. Your file will load only when it is safe. Scanning every file in real-time takes some time which slows down the system’s speed. If the device’s speed seems very slow then you can disable the real-time scanning service. After disabling the function, you must scan the device daily. 

Remove junk from the computer

Antivirus sometimes slows down the device due to the junk files. These files are not available on the malware list so the scanning feature can’t remove them. But when you scan the device, these files start interrupting the process. If you want to run the McAfee scanning process without any issues, delete these files. If your McAfee has the junk cleaner; run it. This tool will find the junk from the device and remove it. You can also check the folders and drives manually for the junk. On your Windows computer, you can clean your device junk using the clean manager. This Windows tool will inspect for junk files and then you can remove them at once. After removing those files, your device starts running at a good speed.

Update the Operating System

Anti-malware programs slow down the system when the OS is outdated. Users must run the Operating System on the latest update. Go to the computer and update its OS immediately. Afte OS, also check for McAfee update. Open Apps and run updates for McAfee and other programs. When a McAfee error is occurring due to corrupted files then you have to repair the setup. For missing program files, you can reinstall your McAfee program and then use it reliably on the PC.
