Re: Windows defender marking NVDA a trojan


Well true, that excludes bgt stuff most likely and if the dev is dead like the one that did virtual recorder.

Most of my false positives are bgt programs.

Some of the hacker geeks on the audiogames forum suspect why that is, but that does mean that for a lot of things especially older software it needs to be excluded.

For the newer stuff thats about, there is enough word out there that compiled bgt code because of how its done is behaving exactly like a virus so devs that can are switching to python for game programming or similar.

Of course those that can.

I know some of the gma stuff is like that, the bsc stuff is also being flagged and since the dev is not doing that anymore its unlikely he will report it same with bgt since the dev has left it alone due to it using older tech.

Its eventually supposed to be getting redone, but he is keeping his secrets close to his chest though when people ask he keeps saying things are coming and they are big so we have to wait.

Thing is, I know what the false positives actually are, but thats no help if there is no actual way to send via email to someone to say that certain programs are not a problem.

And I guess thats what happens with older programs.

I'd idealy like something that would scan all the programs I had, and flag things as a problem but instead of doing anything immediately allow me to exclude and report or simply exclude all the stuff I know is false and report it all at once.

There is always a risk that antimalware programs may accidentally remove an important program or a component of a program because it could mistakenly conclude that the program in question is malware. It has happened and there have been occasions where a program or other component of a screen reader was mistakenly flagged as a virus. However, this type of occurrence, while extremely inconvenient when it happens, is also extremely rare. I've been using computers running Windows since 1994 and have used a variety of antivirus programs during that time and I have never had my screen reader flagged as a virus or trojan. Yes, it can happen but the risk of this happening is low. However, if you plan on using a computer for anything more than writing simple documents trust me when I say that having a good antimalware solution running on your computer is absolutely essential and the benefits far outweigh these small risks. A doctor may mistakenly diagnose your cold symptoms for a more serious condition but the benefits of regularly seeing a physician far outweigh such risks. Windows Defender is now a very good security program. I would encourage you to just enjoy using your computer and to know that, if such a false positive does occur, the developer of that piece of software will do everything to ensure that their software is no longer flagged as a virus as soon as the antimalware vendor can be shown that a mistake has been made.

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?

Yeah some of that software uses autoit and that is known to make viruses.

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

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

     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
