WindowsDefender this program I believe most computer users have heard, as a Windows comes with the antivirus program, basically all computers have been installed and used, compared to the market cumbersome, complex antivirus software, WindowsDefender operation is more simple, only need to be in the settings - update and security can be opened.
Previously for the Windows Defender program, most users are more like to use, the current market of antivirus software is generally useless function is more, the memory occupied is relatively large, and WindowsDefender as a Microsoft operating system built-in program, the memory and consumption of processor performance should be less, but the truth does not seem to be so, recently this program has been proved to have a more serious impact on the user's computer performance, WindowsDefender's wind ratings also fell to the bottom.
A few days ago, there were reports that Defender for Endpoint was causing various problems on customers' Windows 10 systems, and now, there is another piece of bad news, and test results show that Microsoft's built-in anti-malware products can cause serious performance effects on Windows systems on poorly configured computers.
Here are the issues found by Foreign Media caused by Defender for Endpoint:
The memory usage is very high
Black screen issue after signing in (two minutes or more)
Word 2016 and later versions won't open or take a long time to open
Windows Event Viewer takes a long time to display events (remote and local).
After testing, in most cases, restarting a few times may help, but restarting Dafa may not be useful for some users.
As for the problem of Windows Defender's high memory usage rate, it may be caused by a previous memory leak bug, of course, this problem is not a new problem, and even Microsoft has solved it once before.
In the AV-C rating, Defender barely managed to get a "standard" rating because it ranked second from the bottom along with Total Defense Anti-Virus in the assessment. This test is primarily for the following anti-malware products:
Avast Free Antivirus 22.3
AVG Free Antivirus 22.3
Avira Prime 1.1
Bitdefender Internet Security 26.0
ESET Internet Security 15.1
G Data Total Security 25.5
K7 Total Security 16.0
Kaspersky Internet Security 21.3
Malwarebytes Premium 4.5
McAfee Total Protection 25.5
Microsoft Defender 4.18
NortonLifeLock Norton 360 Deluxe 22.22
Panda Free Antivirus 21.01
TotalAV Antivirus Pro 5.16
Total Defense Essential Antivirus 13.0
Trend Micro Internet Security 17.7
VIPRE Advanced Security 11.0
The actual tests were conducted using the latest Windows 10 21H2 64-bit system with Intel Core-i3, 4GB of RAM, and SSD. i3 and 4GB of memory are used to emulate typical low-end computers, which are generally most affected by anti-virus programs.
The test items are:
File copying
Compress/decompress
Install/uninstall applications - use silent installation mode
Launch applications – Microsoft Office (Word, Excel, PowerPoint) and Adobe Acrobat Reader
Download the file
Browse websites – using Google Chrome
The total score obtained in the above test is called the "AV-C score". In addition to the actual tests listed above, synthetic benchmarks for the PC Mark 10 Professional Test Suite were run.
Here's how all the products performed in testing. The image above shows the performance of AV-C, and the image below shows the total score, which also includes the score of PC Mark.
This column basically represents the difference between the total score obtained and the full score of 190. Therefore, the larger the impact score, the greater the impact of the antimalware program on the performance of the test system. For example, if we take Microsoft Defender as an example, its impact score is 24.6, which means that it scored 24.6 points less than the full score of 190, or 165.4 points.
At present, there is no good solution to the negative impact of Microsoft Defender on performance, if your computer configuration is average, then it is recommended to turn off this feature first.
