Re: Windows defender marking NVDA a trojan


false positive and false negative, are two of the main factors that i
never trust and never use security programs, antivirus, antimalware,
not sure about firewalls, but i never used and i am not familiar with
there method and the level of there reliability.
in the previous weeks, maybe in the first days of new year, i sent an
ofline email for you,
but unfortunately i did not recieve your reply and i am waiting for your answer!
God bless you and thanks so much for your helpful replies as always.

Kaspersky and a few others are supposed to be better.

Anyway what I actually said was that these programs at least some of
them detect more false than well who knows.

I have never got a virus in the last 10 years but I have got a lot of
false alarms.

Not sure about win8 etc, but yes you can exclude stuff you know is not a

It would be good actually if you excluded the file you could report all
your excluded files to the maker like microsoft and for each you could
state what it was, etc and maybe get support on it.

The issue I have and maybe others, is that while some of the stuff we
know about, I spend more time stopping false alarms than actual viruses.

I am not sure if thats a good or bad thing but its certainly stopped me
from getting any serious security software.

If windows defender and malwarebytes cause this much trouble with a
false positive, then I really don't want to know what a really good
antivirus will say.

But basically everything on your system is a potential virus depending
on the detections and stuff used.

And with the cloud based ai, I doubt that at the automated level there
is much control.

If you tell them they will fix the issue but there is no reason to think
it will stay fixed.

As a result all the false alarms make the display of the software noisy.

As I said, right now I have so many security holes in my computer caused
by so many folder excludes that if it wasn't for ransomware, I have half
a mind to exclude my entire hard drive or even disable the windows
security subsystem.

However there is always the if factor so I don't.

I havn't run any full system scans in the last 10 years, and I havn't
run any malware software in the last 5 years simply because of this issue.

With the so called inteligent stuff about bgt and maybe some older
software excluded, it seems that every software package needs a security
certification id or something and while it would be nice to get one, I
do wander if I could get one myself for the purpose that the software I
have is not a problem or something.

I know some say I am just unlucky, but on all my other systems with out
blind games, blind software and blind accessible programs there are no
trogens at all and that in itself is a concern, no excludes on any of my
other systems yet.

Maybe I may exclude nvda just because I am concerned but still, maybe I
have over excluded because of all this going on.

did i understand it correctly?
i think that antivirus programs especially microsoft products,
scan the entire system and maybe remove our necessary and important
files even maybe nvda or even other files including html, docx, audio
and video files?
i remember that in one of the iranian websites,
someone recorded a tutorial which explained how to exclude our desired
folders from scanning by deffender.
his tutorial was for windows ten.
does windows deffender on windows 8 and 8.1 does the same things, and
it may removes our essential and important files without worning or
informing us about this matter?

At any rate its clunkey and slow as a language so I wouldn't bother
using programs written in it but you should be able to exclude things.

Yeah when microsoft security etc cleans things it turns user account
control on at 33% by default.

Hi Quenton,

In addition, I always have Defender set to update to the latest
version. I have had odd issues with it in the past. If you are
familiar with Steve's Clock, Defender flagged that consistently. Even
after I allowed it under Defender settings, every time Windows
updates, it flags it again. I had to go into the settings and
manually exempt the Steve's clock folder from Defender scans. Even
then, it always brings up User Account Control when I run it. It
never comes up in start up--even though I have it set to run at start
up. I have reported this to both the program developer and Microsoft
with no change. I am glad that this isn't happening with NVDA on my

Rosemarie and Ron are using Windows 7? Or their Defender hasn't

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

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
