The Windows 10 Operating System is designed to run one antivirus at a time. So, for example, windows come preloaded with Windows Defender, and when McAfee antivirus trial is on a computer, it disables Windows Defender; this is how they sell McAfee.
Unfortunately, McAfee will make a computer run slower, and it costs money. I remove it because I know that Windows Defender is better, and it’s free.
That’s just one example of why it’s important to remove what you don’t need or use. If you mistakenly remove something important, it can be reinstalled, so there is no reason to panic.
In conclusion, keep your hard drive clean by removing any junk programs. When you remove junk programs and or files you don’t need or want on your hard drive, your computer will be faster and remain healthy longer, resulting in a better performing computer.
