Re: Windows defender marking NVDA a trojan


Microsoft updates the virus definitions for Windows 7 and you can download them in the usual way.  I'm not even sure its correct to say that, because MSEE in Windows 7 may use exactly the same definitions as Windows Defender in Windows 10.

Well ms has stopped updating win7 deffs now officially so it won't effect it.

As usual microsoft targets blindness software, I have exclusions for games, recorders and it seems now I will have to do the same to my screen readers and maybe sapi voices?

At this rate I may as well exclude my entire c drive!

How can we the user be secure if we get so many false alarms.

Hi folks,

It was NVDARemote the other week, now it seems it's our turn for Microsoft's random unfounded accusations.  If you try to install the release candidate of NVDA 2019.3, Windows Defender will alert you it has found a trojan in eSpeak NG and blocked it.  The install of NVDA will fail.

As a workaround for now, you can create a portable copy of the RC and that should run fine.  You won't be able to use eSpeak NG.

NVDA 2019.2.1 installs and runs fine, even using eSpeak NG (it uses a different build of eSpeak NG).

I am not sure whether this affects Windows 7 users as well.  I have reported it to Microsoft but I would encourage everyone else to as well.  To be honest, even aside from it being our program affected, this really annoys me.  Defender has NOT found a trojan in eSpeak, its heuristic (machine learning) has guessed that it looks a bit suspicious and flagged it - Ok that happens, but say that, don't say absolutely that a known malicious software has been found.

It took a day or so to fix Defender's virus list and have NVDARemote cleared, so I expect it will probably be within about the same timeline this time around.  Apologies for the inconvenience.
