Windows Defender

[Natter]

Windows Defender has just been updated. As a result, all programs on the FW are automatically deleted.
The antivirus log says Program:Win32/Wacapew.C!ml
Trojan:Win32/Wacatac.B!ml

I, of course, put the deleted files in the exception. However , I would like to understand - is there a problem or not ?

Dear Yuri,

What Windows version are you using ? Are you using latest updates ?

How to check the Windows defender version ?

Here it is working fine

[Natter]

The situation looks like this. On all local computers there is Windows 10 (the latest version),
90% of them have Kaspersky anti-virus installed. The other 10 are running Windows Defender.
Windows Defender is also installed on the Windows 2016 Data Center server.
Problems occurred when copying the file xx.exe from the local computer to the server -
Defender immediately deleted this file. There were similar problems on local computers with Windows Defender

[Antonio Linares]

Have you tried to compress the EXE using upx or similar ?

This may help

[Natter]

I didn't do anything with the file. Everything happened within 1-2 minutes. The
server log says Windows Defender update. I was told that it was the latest version that started deleting files from Program:Win32/Wacapew.C!ml (before that it only warned)

[Antonio Linares]

If you compress the EXE, the error may go away

Thanks, I'll try!
