Hi, downloaded and installed LFS on 3rd of April, Windows defender deletes the lfs.exe and claims that it contains Trojan: Win32/Fethar.B!cl

Did you download it from this website?

Hi, yes, but I think it is my own fault messing with system files, think maybe Windows assumed LFS was problem because it was running. Downloaded again and all good.

I am finding Windows 10 Defender reports LFS to have been infected by Trojan:Win32/Varpes.M!cl and deletes LFS.EXE. Anyone in the same boat?

Just add an exception in the windows 10 defender exceptions. The new defender is the only one that actually helps me now.

The solution: Don't use windows defender or any built in windows anti-virus or anti-malware.

I'm a devoted Kaspersky user, until recently I found that it was preventing me from logging into Word of Tanks servers. Even putting exceptions, or stopping the service entirely did not help, only uninstallation did, so I am back on Windows Defender until hopefully Kaspersky can fix this problem.

Quote from cargame.nl :

Now that we are talking about Windows 10, the funniest thing of all is that Windows 10 has a virus installed by default in the form of a keylogger. Every key you press in Windows 10 gets recorded and send to Microsoft for analysis but nobody seems to care about that. ( http://thehackernews.com/2015/09/windows10-keylogger-security.html )

I'm gonna have to correct you. The correct would be: Windows 10 is the biggest malware and spyware you could ever install on your pc/laptop.
