Hide .EXE into .TXT file extension

Code
i see a fake group he share logs, and he has merged her virus into .txt file. 





the last month i have opened all her txt files at once with notepad, 1 day after that and my channel on the telegram was hacked because the telegram acocunt i have opened it into the vps, so now i tried to download her logs again to get the method that he use it. 





This one, her extension is .txt and everything is txt file and when i upload it to scan it, I see its (Anxious.exe) ;/ 





And i come to scan it via PE i see the signature is with = Microsoft Visual Studio .Net 





Shit how he make it due the txt files cannot be executable.





As i read its a PE (Portable Executable File)



So please is there anyone here explain to me how to hide an EXE into .txt file to be executable when the .txt has been opened.
