Windows Defender might be impacting your build performance

问题

After I updated my Pycharm IDE to 19.2.0 from the 19.1.2. I am getting the following warning:

"Windows Defender might be impacting your build performance. PyCharm checked 
thefollowing directories:
C:\Workspace\Projects\576_UniversityTwitter 
C:\Users\Burak\.PyCharmCE2019.2\system 
C:\Users\Burak\.gradle

Do you think that it is secure, necessary and really improve the performance?

回答1:

You need to exclude those directories in your Windows Security's Exclusion list.

1. Type Windows Security in your windows Search bar
2. Click Virus & threat protection
3. Click Manage Settings under Virus & threat protection settings header
4. Click Add or remove exclusions under Exclusions header
5. Click Add an exclusion
6. Select type Folder
7. Enter the directory
8. You are done

Yes it is secure, necessary and really improve the performance as the real-time scanning is enabled in Windows defender by default. Read this : Minimize the impact of antivirus software on build speed

I faced the same problem with Android Studio which is from same company after the recent update. So what you can do is you will get the directory which is causing this error. Like

Then you need to go to Windows Defender and add these folders to the exclusion in Windows Defender or the antivirus you are using.
