Microsoft Defender is the default antivirus software that comes pre-installed on Windows computers. It is a free and effective antivirus program that can protect your computer from malware and other threats. However, Microsoft Defender has been criticized for its impact on the performance of a computer.
In a recent study by AV-Test, Microsoft Defender was found to have a significant impact on the performance of a computer. The study found that Microsoft Defender increased the CPU usage of a computer by an average of 10%. This can lead to a noticeable slowdown in the performance of a computer, especially on older or less powerful machines.
Microsoft Defender: A Pain in the Performance of a Computer
Microsoft Defender also had a negative impact on the battery life of a computer. The study found that Microsoft Defender reduced the battery life of a computer by an average of 15%. This can be a major problem for users who rely on their laptops for work or school.
The performance impact of Microsoft Defender is due to the way that it scans files. Microsoft Defender scans all files that are opened or executed on a computer. This can be a time-consuming process, especially on large files. The scanning process can also use up a significant amount of CPU and battery power.
There are a few things that you can do to reduce the performance impact of Microsoft Defender. One thing that you can do is to disable real-time scanning. Real-time scanning scans all files as they are opened or executed. Disabling real-time scanning will reduce the performance impact of Microsoft Defender, but it will also reduce the level of protection that you have against malware.
Another thing that you can do to reduce the performance impact of Microsoft Defender is to schedule scans for when you are not using your computer. Scheduling scans will allow Microsoft Defender to scan your computer without impacting your work or play.
Overall, you can also use a different antivirus program. There are a number of free and paid antivirus programs that are available that do not have the same performance impact as Microsoft software.

The best Windows security program
The best Windows security programs are those that offer comprehensive protection against a wide range of threats, including viruses, malware, ransomware, and other malicious software. They should also be easy to use and have a low impact on system performance.
In a recent test by AV-Test, a leading independent security testing lab, a total of 14 Windows security programs were evaluated. The results showed that the following 6 programs earned the maximum score of 18 points:
- G DATA
- Trend Micro
These programs all offer excellent protection against a wide range of threats. They are also easy to use and have a low impact on system performance.
In addition to the 6 programs that earned the maximum score, 8 other programs received an excellent score of 17.5 points. These programs are:
- K7 Computing
These programs also offer excellent protection against a wide range of threats. They are easy to use and have a low impact on system performance.
The 3 programs that received a score of 17 points are:
