Performance Tips in Using McAfee
To enhance the McAfee AntiVirus Plus performance on your computer, it is recommended to keep the system, McAfee and other programs up-to-date. An old version of McAfee software with an active subscription will continue to protect the computer, but the performance and product features are not the same when using the new version that offers improvements and fixes to known issues.
In addition to using an up-to-date software, McAfee AntiVirus Plus also includes PC optimization tools, such as, QuickClean, Defragmenter and Shredder.
The QuickClean feature in McAfee helps improve the computer performance by removing temporary and unnecessary files in Windows. It can be scheduled to remove unnecessary system files and to remove deleted or sent e-mails and browser files. The Shredder feature in McAfee software helps remove private information when deleting files in the recycle bin, temporary files and other user-selected folders, files or drives. McAfee does not have its own defrag program but it does provide a handy menu to launch the built-in defragmenter program in Windows.
The program settings in McAfee's software is enough to run without causing slow performance on Windows. In fact, I tested the boot-time of Windows before and after installing McAfee software:
Using, scanning or updating McAfee software should not cause performance issues if the McAfee software is up-to-date, not corrupted or not damaged. If you are experiencing slow performance or high CPU usage by any McAfee processes, or if the desktop is not responding normally, you should use McAfee Virtual Technician tool to check and fix problems in McAfee program. Also, make sure that the computer is not infected by malware that is actually causing the slow performance or Internet connection problems.
