Windows Defender Antivirus – Microsoft’s Windows Defender Has Been Accused Of Slowing Down The System And Reducing Computer Battery Life. Is This Claim True?
Microsoft Defender is a Windows antivirus software installed by default on Windows computers. This free program can protect your computer from malware and other security threats. However, Microsoft Defender has been criticized by some for the impact it has on computer performance.
According to a new study conducted by AV-Test, Microsoft Defender uses an average of 10% more CPU resources than other antiviruses. This can significantly slow computer performance, especially on older, underpowered models.
Microsoft Defender antivirus, the cause of slowing down the computer?
Microsoft Defender also hurts battery life performance. This study shows that the default Windows antivirus reduces the computer’s battery life by an average of 15%. This can be a big challenge for users relying on laptops for work or study.
Microsoft Defender’s negative impact on battery performance is due to how this antivirus scans files. Defender scans all files that are open or running on your computer. This process is time-consuming, especially for large folders. The scanning process can also be another factor in occupying CPU resources and reducing battery life.
But there are ways to reduce the negative impact of Microsoft Defender performance. One of these methods is to disable the “Real-time Scanning” feature. This feature scans all files at runtime, although disabling it can reduce malware protection.
Another solution you can do to prevent the negative impact of this antivirus is to schedule a scan for a time when you are not using your computer. Scheduling scans allow Windows Defender to scan your computer without affecting work or play.
But the last resort is to use an alternative antivirus program. Some of these programs, which are available for free or for a fee, do not have the negative performance impact of the Microsoft program.
Is Microsoft Defender good at detecting viruses?
Despite the impact on computer performance, Microsoft Defender is a good and functional antivirus program that effectively detects and blocks malware and is free to use. However, if your device’s processing performance or battery is affected by this program, it is recommended to use another antivirus.
